The act of giving/receiving a blowjob while playing one of the greatest xbox 360 games of all time, Elder Scrolls V: Skyrim.
As opposed to popular belief, this has nothing to do with the term "rimjob" and can only be pulled off when you have a woman awesome enough to put up with it. As an added bonus, one can scream "Fus Ro Dah!" upon ejaculation for added humor.
"Dude, I heard Kyle convinced his girlfriend to give him a skrimjob!"
"He is DEFINITELY getting a high-five the next time I see him!"
