Full ass sticky back

When you put your balls up someone's ass but leave your dick out so you can jack off on their back.

:oh man Why's your shirt all wet?
:Someone stuck their balls up my ass but left their dick out so they could jack off on my back.
:That sucks, you got a full ass sticky back

Back ass

When a person has no ass and their crack looks like its in the middle of their back. They're flat as a board on their back end.

"Damn.. did you see his back ass?! I couldn't tell where his ass starts and his back ends.."

back that ass up

when a girl puts that delightful arch in her back, and sticks her ass out in a erotic/sexually suggestive manor, often accompanied by a "booty dance", that brings shear delight to the males species.

"did you see her back that ass up, playboy? it almost brought a tear to me eye, and a 2x4 to my pants!"

"did you see lucy liu bending over in the drive-thru scene in charlies angels?? ddaaaaaaaaamn, it was delightful! that the essence of female perfection!"

1. Back the fuck up. Get out of my face. Calm Down
2. Insist a female shake and rub her ass against you when dancing.

1. Damn nigga, back that ass up before I get crazy up in here.
2. Come here girl and back that ass up for me.

back of ass

Terrible smelling, like warm, stale, canned ass, but worse. Nasty!

I know that you guys are used to your apartments smelling like back of ass, but don't trash my place.
