What is Piss Pot Pete?

There was a girl named Casey Brown, she claimed no man could pin her down.

Over the hill came Piss Pot Pete with a hundred pounds of swinging meat.

Pete was fast and made a pass, stuck his dingey up Casey’s ass.

Casey was smart and ripped a fart, blew Pete’s dingey all apart.

Back over the hill went Piss Pot Pete with a hundred pounds of shredded wheat.
