Six Back 

The bulges protruding from a fat chick's back when her dress is too tight. Usually above and below her bra and the spare tire aka love handles.

"I’ll be out the gate by eight / in the spoon by noon / fixed by six / and back in the pen by ten!” 

The heroin junkie merry-go-'round:

Release from prison-back to using dope-re-arrest.

The addict's vicious cycle.

Johnny Threefingers: "Heard you're getting out of this craphole today."
Harry Hophead: "Pfft...well, I'll be back...you know me, man... ""I’ll be out the gate by eight / in the spoon by noon / fixed by six / and back in the pen by ten!”"

Backwards Six-pack

A term used when an overweight person has sections of flab across their back. Kinda like a six pack but the wrong way round.

Guy 1: "Dude, dude... check out the backwards six-pack on that guy!"

Guy 2: "Woah, he should really get some excercise..."
