Jack Dempsey

A "Jack Dempsey" refers to one beating his meat very aggressively, as the legendary boxer Jack Dempsey flogged his opponents.

Dude, I got so excited over that midget porn I was watching that I stole some face cream from my sister's make-up bag and gave myself a "Jack Dempsey". Now my pecker is sore.

A man who owes the majority of his fame to a fish.

I didn't know who Jack Dempsey was until I went to the "aggressive cichlids" shelf in petco
