A bumper biscuit is when you take a dump on a nemesis', rival, or friends car bumper. Mostly done by high school or college age boys, well known at the Virginia Military Institute (VMA).

Dude, all that corn and nuts paid off. I dumped a bumper biscuit on that idiot Jason's car that was worthy of the yearbook.

Two or more hefty female college athletes - usually bowlers, who engage in mutual genital stimulation thereby "bumping" their biscuits together.

Those two bitches bowled a hell of a game. I'll bet they go home and bump biscuits. Or simply "Biscuit Bumpers!!!"
