back boob

a fatty deposit on the back that hangs in such a way that it resembles a nippleless breast. May sometimes result from a bra that is too tight, causing temporary back boobs. Mostly seen on very fat women or men with manboobs.

"He's got a sick fetish--he goes to the nude beach just to look at back boobs."

back twin

If a stranger looks identical to one of your friends from behind, then the stranger and your friend are back twins.

Guy 1: Hey Ben, what's up?

Guy 2: (turns around) Huh? I'm not Ben.

Guy 1: Oh, sorry, you're just Ben's back twin.

look-back

When someone glances at you, looks away, then immediatedly looks back. Like a double take, but sexy.

"I got 2 look-backs from total hotties today"

"Dude that wasn't a look-back, she had something in her eye!"
