Backing the bus up

Dirty dancing with an ass grinding Crotch movement as it’s Main move

She was really” backing the bus up to me”, and her boyfriend did. Not like it one bit.

Eisa back up

When your reversing the van and a camp spot

Ay cmon lad Eisa back up

Back-up-break

When someone stops at a red light next to an old person, slowly starts backing up, and yells "put on your brakes!" at them.

I can't wait for the day I get to back-up-break some unsuspecting old fart!
