gack back - That crummy feeling in your back when you've been slumped ov

That crummy feeling in your back when you've been slumped over like a f***ing slug after a long night of doing lines and snorting meth.

I woke up with my back screaming at me like it was in a f***ing band.

I did so much meth I think my back is now a f***ing meth dealer.

I was slouched over so much my back is now a f***ing slouch.
