RBFD 

A REALLY big fucking deal. For when a "big fucking deal" doesn't quite capture the magnitude of the pressing matter at hand.

Senior 1: Dude secondary school reports for college apps are due tomorrow.

Senior 2: BFD
Senior 3: It's a RBFD...

RBS 

Raging Boner Syndrome

When one conceives of a boner that results in a massive erection that is capable of being seen from under layers for clothes.

"I had RBS the other day at dinner, and I couldn't get up to walk without having to think of Ellen Degeneres, the Zima man, cow manure, and my mom naked."

See also Ron Burgundy in 'The Anchroman'.

RBS 

Acronym for "Raw Butthole Syndrome" which occurs when you wipe too many times throughout the day due too diarrhea or some kind of overly active and greasy poop. It is that burning sensation and pain that occurs.

Dude my RBS is the worst after that last puddle of mud I spewed.

RBM 

Random Black Man; usually found in parties around college campuses. Can often be found dancing shirtless near the stereo after only a few drinks. Nobody at the party knows this man, making his blackish presence random.

Partier 1: Dude, who's that shirtless nig dancing near the stereo?

Partier 2: I don't know, looks likes an RBM to me.

Partier 1: Quick, hide the Hennessey!
