Back

Could be something moving backwards or maybe the return of someone/something.

"Yo, bro did you hear about rregretzz?"
"No what happened?"
"He is back!"

tweek back

A strenuous and/or painful sensation in the lumbar region, middle, dorsum region, or entire back, due to remaining in uncomfortable positions for unnecessary prolonged periods of time while high on methamphetamine.

Christopher missed work today due to a chronic case of tweek back.

The Back Ali

Usually administered when someone is in the goat position (I.e.. when you tuck you dick and balls between your legs and close them. Thus displaying them proudly behind you, as oppose to them being normally in front.)

And then the girl performs fellatio on him.

I was showing my girlfriend the goat when she started performing The Back Ali.

Double hunch back growly

This is the process of tucking one’s dick and balls pushed back between the legs to look like a female. The double hunch back is the 2 balls back and growly is because it kinda hurts….ref Silence of the Lamb, this was done in the movie by the killer.

Dude, that is an epic double hunch back growly, nicely done!
