backin

When you are fucking your woman from behind, you violently smak her ass to a point of exhaustion while removing your penis and inserting a dildo in a gracious act of liberal democracy.

As Jack boned his woman from behind, he decided it was time to start backin and show his girl some decency.

Big backin

The act of eating like a big back. Hunched over a huge plate of food, a big back has to advance his shoulders to get his face over the plate, or else there's a stream of stains down his shirt. With his shoulders forward, his upper back is "big".

That dude is big backin that food

Stop big backin, we've got plenty of time to eat.
