An individual engaged in anal intercourse, whose facial expressions resemble that of a chimpanzee. Often seen in porn flicks by bad actors and egotistical steroidal junkies who think they are god's gift to sex.
Check out that freakin' bung monkey banging that back door. Someone should shove a banana in those lips!
