Dirty Fucker

A scummy swamp abomination of a drink, comprising one part coke and one part beer (preferably a heavy, yeasty one). The head on this evil motherfucker leaves a filthy brown residue on the glass wherever it touches, which crusts magnificently, creating a vengeful spectacle for hungover eyes the next morning.

The night was going swell until Max suggested we whip up some Dirty Fuckers . The rest is a brown blur.
