gambeerbating 

The simultaneous acts of video-gaming, drinking beer, and masturbating.

I don’t much feel like going out tonight, I think I’ll just stay home gambeerbating.

John has been so reclusive lately, all he does is drink beer, play video games, and masturbate. He’s on a gambeerbation binge.

Gamerbating 

The process of performing a "guilty pleasure" in a video game, gamerbating can occur by entering cheats, finding glitches or easter eggs, or anything that makes the game more enjoyable.

Dave: How are you so far in the game already?
Tom: Oh, i spent all night gamerbating.
