Punched Humphrey

When a male and female are having sexual intercourse, and the penis slips out of the vagina and penetrates her asshole, the male's Punched Humphrey (Humphrey is a term for shit).

I was having sex last night and accidentally Punched Humphrey! Needless to say, she was feeling pretty sorry for herself.

Humphrey

A slang term for a shit.

Bob: I almost split the shitter this morning. The Humphrey I did was almost as big as the bear.
Jim: Had a little too much Sultana Bran for breakfast, then?
