What is Brake Check?
1.
While driving, hitting your brakes really hard to scare the crap out of the jerk driving two inches from your rear bumper.
Checking to make sure they have enough time to brake without rear-ending you (pissing them off).
This guy is driving way too close to my rear bumper, time to brake check him.
