fat back

The layer of fat that runs along the animal's back. It's VERY salty, and yet you can't stop eating it.

I don't care that it's making my blood pressure sky rocket, pass me another piece of fatback!

Lobster-back

An archaic slur for a British person - still used humorously today (British Army used to wear red coats - lobsters are red).

That dirty Lobster-back has bad teeth.

pass it back

When after cumming into a someones mouth you ask them to "pass it back", the sperm is then transferred from the original recipient's mouth to it's original owners mouth by any means. After this takes place the sperm is then swallowed by it's maker.

Your girlfriend is giving you head, and you cum into her mouth; however, you ask her not to swallow, but to instead, pass it back, put your own sperm into your moth so you can swallow it.

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.

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.
