Something you'd call someone who is small. Sometimes it is used as a term of endearment but it also can be used as an insult or a way to make fun of a short person. The person being called Chibi Chan is in denial about being short most of the time.
Tall person : Hey, Chibi Chan!
Short person : Stop calling me that, loser!!
Tall person : But I want nothing but to love and support you! You repay me by calling me names?
Short person : Whatever. Go away!
The child version of N.Italy in a series called Axis powers: Hetalia. He works in Austria's house as a maid. He was mistaken for a girl by many other characters since he was often wearing girl clothing because of Hungary dressing him up. This resulted in the Holy Roman Empire (HRE) to fall in love with him.
Keiichi Maebara's super hero state in which a super deformed version of himself flies around naked. The theme song is surprisingly catchy and annoying... but it's still hilarious.
This is a joke originating from Nyodude's Higurashi Parody Fandub.
Keiichi: "This looks like a job for... Keiichi's Chibi Angel Bottom!"
Keiichi: *singing to the tune of TMNT* "Keiichi's Chibi Angel Bottom, Keiichi's Chibi Angel Bottom, Keiichi's Chibi Angel Bottom, heroes in an ass crack, chibi power!"
Shion: *punches Keiichi* "This is why I go crazy and kill people...!"
