Ahoge (literally idiot hair) refers to the noticeable slim forelock of hair that sticks straight up from a character's head. Originally a hairdresser term for the "stupid hairs" or cowlicks that will not comb down, it later mutated into a literal reflection of a person's intelligence. Thus Idiot Hair suggests that a character is stupid, naive, or strange. (This suggestion is usually accurate, but not always - sometimes a serious character just has funny hair.) Idiot Hair is not to be confused with the two-stranded antennae-style hair, most recently popularized by Love Hina or Ah! My Goddess.
