Back Mouth

Another name for a person's anus.

If you don't shut up I'm gonna make you eat that plate with your Back Mouth.
I was fucking this chick in the Back Mouth the other day and she started convulsing. It looked like a toothless horse eating a carrot.

back rev

To throw one's car into neutral and push down on the gas pedal hard while still rolling in order to rev one's car up without increasing the speed of the car. This act is usually done to show displeasure with another driver or pedestrian.

I drove back around the block so I could back rev at that girl who flipped me off.

wet back

Racial Slang. Refers to any Hispanic
immigrant, particularly those of illegal
origin (the implication being that a wet
back results from crossing river borders
by swimming). Generally considered to be
a slur, offensive. Also "wetback".

Every summer, they hired a bunch of wet
backs to work the fields, and paid them
under the table.
