A man who tries to "accidentally" jam his dick in his girlfriends ass who is clearly not into anal. A derivative of hamburglar, except it applies to ass. An ass stealer, in short.
Dude, Jane slapped the shit out of RJ last night and then broke up with him. That lazy eyed ass mungler tried to jam in his 3" cock in her bong hole one too many times.
