Pittsburgh Pooter 

Upon completion of intercourse with his girlfriend, the boyfriend ejaculates on his girlfriend's stomach and on her inner thighs. He then proceeds to stick his naked ass in her face, rip a huge, wet fart, while yelling "ITS OVER BITCH!" It is a common practice in the Pittsburgh area to break up a relationship.

Paul: I couldn't stand my girlfriend anymore. She pushed me over the edge, so I ended it.

Mike: Did you do what I told you to?

Paul: Ah, hell yeah! I nutted all over her and then gave her the old Pittsburgh Pooter!
