RBA 

Random Boner Attack: when one randomly gets a boner.

RBA's often come about while riding in the back seat of a car or in class. When someone goes to get up to do something and they have a visible bulge or are pitching a tent

RBFV

Random Burning Fire Victim- hypothetical persons invented in Squat VS. Deadlift discussions to assess "functionality"; they are most-commonly unconscious.

Felix: "Yeah, but what if I'm a firefighter or something?"
Gary: "You should deadlift. Zercher-style is preferrable. The barbell will have toughened your forearms to withstand the RBFV's residual heat."
Felix: "Are you sure?"
Gary: "Squats won't help you when you come across that RBFV!"

RBux restock

RBux is a free robux rewards website, it's kinda good but the restocks take forever. This time the restock is a myth, RBux will never restock. They keep telling us they will restock but every day passes and nothing happens...

Friend: Yeah, you can count on me, I will be coming tomorrow
Tomorrow:
Me: Oh c'mon, you didn't have to lie like that, this isn't the RBux restock...
