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!
