"If men could control their dicks, do you think we would wake up every morning hard? Do you think I wanna deal with that in the morning? No, I just wanna get some coffee, read the newspaper."
Franklin Ajaye

An erection isn't always wanted, or even the result of sexual arousal. Such a "Raging Stiffie" may not be erotic, but it is a staple of comedic fiction.

Common causes of an unwanted or unexpected erection prevalent in fiction include:

  • Overactive hormones: An unwanted erection with no or minimal stimulation is a fairly common (although hardly universal) side effect of being a male in real life. In fiction, sufficient reliance on Refuge in Audacity or a sufficiently adult target audience enables this trope, allowing for comedic consequences and an exploration of "coming of age" issues.
  • "Morning Wood": In real life, some males often wake up with an erection, particularly if warm. In fiction, any treatment of this inevitably degenerates into seriously off-color comedy. The correct medical term for this is nocturnal penile tumescence.
  • Viagra: This wonder drug does have the comedic effect of inducing erections that last a long time even if they are unwanted and the situation is inappropriate.

Most of the time this is Played for Laughs, and doesn't last longer than a few minutes. However, the condition known as priapism (prolonged erection) is dangerous, and can lead to penile amputation. (Ew!) That's why Viagra commercials tell you to "seek immediate medical attention if an erection lasts for more than four hours."

Just as a point of note, men have erections from the time they are infants. (Double "Ew!") In fact, a male has his first erection inside the womb. (Triple!) Unfortunately, since Most Fan Fic Writers Are Female, it's not an uncommon trope for a male character just on the cusp of puberty to be "shocked" that his penis has suddenly become rigid. This would not shock any male. What shocks males is that it's now happening so often and at the wrong time.

For sneaky instances in manga, look for the sound effect "kin kin kin" combined with any degree of blushing or nervousness.

Contrast The Loins Sleep Tonight. See also Something Else Also Rises. May be caused by a Potty Emergency. Jizzed in My Pants is this trope taken to eleven.

Examples of Raging Stiffie include:

Anime & Manga


  "Come on, GET UP!" *Beat* "You stupid pervert, I didn't mean to get THAT up!"

    • Also, his "thermal expansion" when overhearing Asuka and Misato at the hot springs.
  • The morning version is practically a defining trait of Ryo from City Hunter (manga only). As he says, "It just means I'm healthy!"
  • The second volume of The Kindaichi Case Files manga had Hajime suffer from this. Worse yet, Miyuki thought it was something in his pocket and started going through them. The next scene Hajime has a slap-print on his face.
  • In the Higurashi no Naku Koro ni manga, Mion comments on Keiichi being "perky" in the morning (with an arrow following her gaze to his crotch, if the innuendo was too subtle for you). She may just be teasing, though... Keiichi does make a comment on how its her fault he'd be "perky" though.
    • In the first arc of Kai, Rena survives becoming a zombie in Zombie Tag when she induces this in Keiichi.
  • In Genshiken, Sasahara is implied to have one during his date with Ogiue after she whispers in his ear.
  • Gantz: Teacher, Kurono's got a hard-on!
  • The hentai Very Private Lesson is all about this trope. Aya, a 16 yr old high school student, pretty much does nothing but give her teacher Tairaku one unwanted stiffie after another. She even says straight out that she teases him because he's so good at controlling his urges. And the penalty if he loses control: among other things, being cut up slowly by the local head of the Yakuza, who just happens to be her father.
  • In Full Metal Panic, the novel version of End of Day By Day, when Gauron was reminiscing about how he first saw Sousuke, as well as talking about how Sousuke was a beautiful Assassin Saint that he wanted to kill and rape, Gauron starts taunting Sousuke... and through the darkness, Sousuke notices something from the middle of the bed that seemed to be rising and "beckoning" him. Since Gauron had no arms... or legs... and there's really nothing else other than that thing between his legs that could possibly be coming from the middle of the bed... yeah. It's sufficient to say that Sousuke was thoroughly freaked out.
  • The second episode of Trapeze is about this, in the form of an erection that lasts for days. Eventually it's revealed to have psychosomatic causes. (it is acknowledged that this kind of priapism is unrealistic)
  • Makie notices that Negi is growing (NSFW)
  • In Ladies versus Butlers!, Sanae straddles main character Akiharu's lap in order to scrub his back (she apparently didn't think it through very well) and can't seem to work out what is poking her in the butt [1] (NSFW)
  • Seiji in Midori Days: it's not his fault his body works just like any other boy's!
  • There is a notorious panel in Parasyte where the main character (who has an alien in place of his right hand) gets aroused... and the alien, reflecting this arousal, turns into a giant penis.
  • Saiga of Speed Grapher gets an erection whenever he takes exciting photographs with his camera.
  • The soft-core hentai series Magical Twilight finds the protagonist, Tsukasa, getting one of these when the witch, Chipple, tries to clean up a drink she spilled in his lap. This being a hentai series, this naturally went exactly where you'd expect it to go.
  • Oyasumi Punpun: Punpun goes on a date with a classmate and has a boner the whole time just from being with a girl and anticipating getting laid. She doesn't notice it. Goes into Squick territory when he tries to rape her.
  • Keitaro of Love Hina has been caught with one of these more than once throughout the series, due to the first two types. Much to his embarrasment.
  • In Tenchi Muyo! GXP this trope shows up in an early episode. Since main character Seina won't wake up and get out of bed his friend Kiriko tears the covers off only to discover his morning wood, he is shown in the very next scene eating breakfast with a large red (undeserved) slap mark on his face.
  • Happens in Boys Empire — Hitomi, riding on a train with Makoto, is less than thrilled about having caught him in bed with his mother and is busily griping about it; thinking about it, combined with the train's jostling, causes Makoto to get one of these. She mutters "You're hopeless" before dealing with it.
  • In the Hentai anime OVA Darling, the husband enters Super Erection Mode! when he's getting inspiration for the dirty manga he draws. A bunch of elephants run by when he does.
  • There is a G-Rated version of this trope in Brock whenever he meets a charming lady, regardless if they are already married or not. Basically, it's gotten to the point that when he doesn't have this around Inexplicably Identical Individuals, he starts getting suspicious (often he's right; it's Team Rocket or someone else disguised as the Nurse Joy or Officer Jenny).
  • The titular character of Hajime no Ippo is repeated victim, as if being mocked by his gymmates for his Gag Penis wasn't enough. One of them happens in the water, when he sees his Love Interest in a swimsuit for the first time.

 Kumi: Be careful Nanako, his muscles are very stiff.

Nanako (smiling): They are indeed.

Ippo (thinking): Not that one!

  • The Umisho manga occasionally shows Takeda's reaction to the Fan Service surrounding him.
  • Satou gets one twice in Ben-To — one in Episode 5 while Matsy takes care of him after he gets the shit beaten out of him by the Monarch and another one in Episode 7 after seeing the Brunette's top fall off. He manages to weaponize the latter by using it as a rudder. It Makes Sense in Context.
  • Heavily implied in a Wandering Son chapter. Shu is getting a massage by her girlfriend Anna, but ends up getting one of these... and her older sister Maho walks in right when it happens, causing a stir. This is an even bigger issue since Shu is a trans girl.
  • Played for Drama in Rei-Lan: Orchid Emblem: A young man named Doug gets one as he's being Forced to Watch how his girlfriend, the titular character, is being raped by the Big Bad, and logically he's mortified. Said Big Bad's Creepy Twin floozies notice his predicament and begin mocking the poor guy over it!

Fan Fic


  • When Charlie Sheen's character came Back for the Dead in Scary Movie 4 this was part of his death. He accidentally swallows a whole packet of Viagra in a failed attempt to overdose. His penis inflates to ridiculous proportions and he throws himself out of a window, landing face down, with his hips nowhere near the floor.
  • Anchorman: The Legend of Ron Burgundy:

 Veronica: Mr. Burgundy, you have a massive erection.

Ron: Really?...Yes, I do...Um, I'm sorry, it's's the pleats. It's actually an optical illusion. It's the pattern on the pants. It's not flattering in the crotchal region. I'm actually taking them back right now. Taking them back to the pants store...Oh, this is awkward...I'm gonna walk...I'm gonna walk this situation off...and I will see you later...Nothing to look at...Go back to work, everyone...Don't act like you're not impressed.

  • The Proposal: Sandra Bullock and Ryan Reynolds' characters are posing as a couple, and try to act as if they were just spooning.

 Sandra Bullock: What is that?!

Ryan Reynolds: It's... The Morning.

  • Played hilariously in Sorority Boys. One of the boys Disguised in Drag is taking a shower when the sorority's president playfully joins him. "Stop poking me in the butt!"
    • It should be noted that the president (and also the love interest of the guy she's taking a shower with — both when he's disguised as a woman and when he's a full male) is very near-sighted.
  • In The Man With Two Brains, Steve Martin is teased by his new bride, and when he steps over to the french doors (lots of little glass panes), we hear the sound of glass breaking. He looks down.

  • Road Trip. Old man + Baywatch + Viagra.
  • Chev Chelios gets "a steel hardon" after taking too much epinephrine in Crank.

  • Occurs in Peep World with Nathan, during a medical exam based off his premature ejaculation.

  • Emperor Nero uses this to his advantage in History of the World Part One to find out which of his wife's attendants is an imposter. (The rest are eunuchs.)


  • Morning wood comes as an unnerving and mortifying shock to a woman who has switched bodies with a male friend in Curse The Dawn.
  • The Fionavar Tapestry offhandedly mentions this as a character gets out of bed and, with minor difficulty, into his breeches.
  • Nimue Alban in David Weber's Safehold books learns just how "fully functional" her robotic body is when, as the male Merlin Athrawes, he learns that the Safeholdian version of rugby is played in the nude, and Nimue, for all her body was male, was still a woman where what was attractive to her was concerned.
    • When Cayleb learns Merlin's true identity and is reminded of this incident, he finds it absolutely hilarious.

 "Oh, my God! That was why you stayed in the water! Why you were so damned careful about that towel!"

  • Sir Harry Flashman finds that his rather ragged trousers are quite incapable of disguising his — er — respect for the shapely but quite mad Queen Ranavalona of Madagascar.

  • Something like it happened to Kryten on Red Dwarf when he became human; though it didn't cause embarrassment so much as curiosity. And two polaroids.
    • Word of God says that Craig Charles's funny reaction to being handed the pictures was real, because the 'prop' pictures were replaced with real ones at the last minute without telling him.
    • In another episode of Red Dwarf, in order to win a basketball match, Lister and Rimmer spike the opposing team's drinks with a 'virility enhancement drug'. As The Cat put it, "try moving fast with a fishing pole in your pants!"

 Carter: ...sir?

O'Neill: It's my sidearm, I swear!

  • '80s Hair Metal band Dangerous Toys had a song titled "Sportin' a Woody"

Video Games

  • Happens to Shiki waking up one morning in the Visual Novel Tsukihime. His personal Meido who comes to wake him up is either oblivious to why he's staying under his blanket or is deliberately trying to embarrass him. Hilarious, right? Then on Ciel's route, it becomes extremely unfunny when he can't get it down because his body is no longer solely his own, and now Shiki has urges to kill people and gets off on it. This requires... you guessed it... a Deus Sex Machina to resolve.
