asstmer

Term used to describe an ass who gloats about being the "master" of some skill or game.

Ralph: Dude, I just owned you in that game of Pokemon! You will never beat me. I am the master!

Mark: I have to hand it to you, Ralph, you are a true asstmer indeed! Now get the hell out of my house before I pound your butt . . . but leave your Chickorita card. She rocks!
