Door Check

I was biking down broad when some lady door checked the shit out of me. I wish she wasn't so stupid.

Door Check 

The act of driving close to the sidewalk, when a pedestrian enters striking distance, the person in the passenger's seat throws the door open hitting the pedestrian.

Another variation is the "Pump Fake Door Check". It requires two passengers. The person in the front throws their door open just wide enough to make the pedestrian flinch, then they close their door. The passenger in the back seat then hits the pedestrian with his door even harder. Everyone in the car then screams, "That's two for flinching!"

Strong: "Dude! Door Check that mail man!"
*wham*
Turner: "....i think we killed that guy."

Door Checker

A term for an individual who is caught in an embarassing moment--especially when that individual tries to 'play it cool' and act natural through this awkward moment.

"Paul is such a door checker, I can't believe he flew off the back of the treadmill at the gym today... I hope his black eyes heal up by next semester."
