A male prostitute who covers himself and his partner in a thick coating of shit.
I am going to buy a dirty man for tonight!
by TetrisandRubiks January 17, 2012
A man who has not bathed, wears a beanie, and has a dirty beard (see "dirty beard"). Usually has sex with many women but in turn has probably made them dirty women by just touching them. Dirty men are usually seen working in convienience stores, fast food, or just walking aimlessly at all times of the day.
"Anyone from Linkin Park is a dirty man."
