cari istilah yang lo mau, kaya' ratchet:
The sound that occurs when being slapped across the face by a big penis. Usually the head of the person being exposed to the slap slap will move from right to left during this procedure.
His penis was so big that I could literally hear a "slap slap" while he was hitting my face with it.
