hihi means "Baboon" in English.
- You Baboon!
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.
