We're you do a line of cocaine off of someone Else's ass starting from the crack and going down.

Babe you wanna do a dirty bump?

dirty bumper 

When you are racing in the house like you have a tampon in the wrong hole and eyes wide open like the first time you had anal... cause saying "I'm crowning" is the nice version of what is going on at your back door.

Dammit, outta my way (waddling to the bathroom), I have a dirty bumper!

Dirty Bumper Car 

When a man is smooshing with a woman in the doggystyle position, she defecates all over his waistline, and he continues to have sex with her; smashing the feces all over the two of them, while ramming each other like bumper cars

After an insane night at the bar, Bob Combo was nailing some strange from behind, when all of a sudden the coyote ugly shit all over his man pubes. Bob contemplated quitting, but instead he just kept on trucking. Ultimately giving the chubby vixen her first dirty bumper car.
