Fap-a-saurus Rex 

This is another usage of the word "fap", which means to masturbate. There are three distinct levels of fapping and Fap-a-saurus Rex is the most extreme. It is someone who masturbates constantly, during every waking and non-waking moment. This is a person whose hand you never want to shake. This is the type of person who does not eat, shower, or sleep, because it takes them away from fapping.

Joe Schmoe: "Dude, have you seen Bill recently?"
Tim Fuckis: "Yeah about three weeks ago. That's when he became a Fap-a-saurus Rex."
Joe Schmoe: "Damn, so that means he does nothing but fap? Not even eat or sleep? And I thought I was bad being a Fap Master"
