Pulling a practical joke. Before Jeffrey Dahmer was a psycho serial killer, he was an alcholic class clown at his high school. Classmates reffered to any practical joke or crazy antic as "doing a Dahmer". Later, it would come to mean "killing, having sex with, and dismembering a man".

see the A&E Biography of Jeffrey Dahmer for the actual mentioning of this phrase

Joe: Kevin was just doing a Dahmer right in the middle of class
John: Oh my God! The teacher didn't stop him?!
Joe: Dude, calm down. It means played a joke.

Cutting off a mans cock and balls, freezing them in a bag to use as a anal sex toy once frozen. Upon freezing, repeatedly sick the solid cock in your own arse whilst eating the remains of the already dismembered body.
