hihi ヒヒ

Translation

hihi means "Baboon" in English.

You Baboon!

hihi ヒヒ may be used to call a middle-aged man a "leecher," specially used toward a dirty "old man," oyaji おやじ.

hihi written with kanji is 狒々.
This word contains non-jouyou kanji 常用漢字.

hihi may also be written as 狒狒.

The kurikaeshi 々 symbol repeats the kanji that comes before it, so 狒々 is the same thing as 狒狒.

Scientific name: Papio.

Beware: some kanji that are difficult to handwrite are easy to type on the computer, which may skew the usage statistics.
