derf batter 

The act of 2 buck naked men in a horny frenzy come together taint to taint and mash them together until the sweat mixes with ass juice forming a burnt buttery looking substance that smells of Axe body spray, Ball sweat and Shit!

By the smell of him, I'd swear he was out making Derf Batter last night!

Someone who ruins your whole weekend just by stopping by

We were just hanging out after the party having some beers and listening to music, and then some derf ass turkey stopped by. After that, everybody just wanted to go to bed.
