Funnel Madd Beers

This involves the popular art of funneling not just one, not even two, but funneling madd beers. Typical situations for this are crunk parties involving women, which evidently leads to the other form of FMB, Fuck Mad Bitches. The two definitions are most often used together.

Ken: What's the game plan for the night?

Ken: Foolproof plan homie. Shit's gonna get real.
