Back da fuck up nigga

Back da fuck up nigga. If someone tells you to back da fuck up nigga, you better do as he says....
or you'll get smacked the fuck up.

Some youtube prankster came up to me asking if I wanted to kiss his ass. I said 'back da fuck up nigga.'
He wouldn't so I gave him a solid right hook and broke his jaw.

up the back

to bang someone in the ass.

She said to me, "You can go up the front or up the back."

And I thought to myself, sweet, this chick wants me to bang her in the ass.

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!"
