Masturbathon 

Not to be confused with masturbathong, a masturbathon is a marathon in which one masturbates constantly for a set period of time. Can also be the opposite in which one does NOT masturbate for a certain period of time.

Guy 1: Hey man, I'm going to go on a masturbathon tonight.
Guy 2: Nicee, good luck.
