Dirty Kid

Near opposite of the Dirty Old Man or Dirty Old Woman, where a kid is ridiculously young, but still has some signs of... "interest". What's most notable is that often, kids or babies are allowed to cop a feel, simply because it's said that they don't understand what they're doing. This kid, on the other hand, is aware of this in one or another way, which will almost always Played for Laughs.

Note that there seems to be some level of Double Standard, since most of the examples seem to be male. If the kid is sitll dirty when they reach their teenage years, they're a Hormone-Addled Teenager

See also Kidanova, which deals more with the romantic aspects, as opposed to the sexual ones.

Not to be confused with The Pig Pen, who is filthy in a different way.

Examples of Dirty Kid include:

Anime and Manga

• Johji from the Death-T arc in Yu-Gi-Oh!.
• Shin from Shin Chan.
• Momoka from Mawaru Penguindrum. She went missing as an elementary schooler. Her Diary is very detailed and specific about how her future life would have gone. This includes sexual activities with her prospect Victorious Childhood Friend, Tabuki.
• Hajime is re-written as this in the Ghost Stories dub. In the original he was fascinated with Satsuki's panties, but in a more innocently immature way.
• Machiko's students in Maicching Machiko-sensei are constantly Hell-bent on stripping her naked.
• Megu Kanzaki's adoptive brother Rabi in Majokko Meg-chan.
• Pictured above: Momonosuke aka Momo from One Piece not only is this, but he takes advantage of it as much as he can with both Nami and Robin, and even taunts the jealous Sanji, Kin'emon and Brook about how he can get away with such antics.
  • It's In the Blood: Momonosuke's father Kouzuki Oden used to go to the local Red Light District at age six and grew into one hell of a Chivalrous Pervert.
• Nobita and Tsuneo from Doraemon have traces of this at times.
• The titular character of Naruto is one at age 12, which certainly explains the... infamous Sexy no Jutsu.
  • His friend Konohamaru also qualifies, especially when he buries his face in Lady Tsunade's Gag Boobs and, to no one's shock, he learns the Sexy no Jutsu from Naruto himself
• Subverted with Meliodas from Nanatsu no Taizai, who's a huge pervert to his girlfriend Elizabeth... but is actually a millenia-old demon with the looks of a preteen boy

• Played for Drama in House, where a little boy whose younger sister is the patient of the day becomes VERY obsessed with Cameron. At first he just offers her flowers, then he pinches her ass, then he's VERY jealous of her love interest Chase...
