In a picture posted on the GameFAQs forums by AlienNine, of his girlfriend's back tattoo, there appeared to be a boob on the back, slightly below the arm.. Yes, a boob on his girlfriend's BACK. Of course, even the dumbest little 12 year old could figure out that it's fat, but...we JUST don't care. Since that day, the "back boob" has become the new...well, the new "confirm/deny". That easy.

The practice of holding a hand out the window while driving at high speed and "cupping" the oncoming air as though it were a boob.
HMB: Hey, mind if I open a window?
DTM: Sure. Did you fart?
HMB: No, I just want to grab an air boob.
DTM: Ahhh, yes. Air boob time!
HMB: AIR BOOOOOOOOB!
(Both roll down windows, grab air boob.)
DTM's dad (confused): ..."air boob"...?
DTM: Sure. Did you fart?
HMB: No, I just want to grab an air boob.

A bustier or a low cut top paired with a push-up bra, creating the effect of breasts served on a platter, ie "Would anyone like some boobs?"

The underside of a boob, when revealed without a clear view of the nipple, as when one is privy to the view up a woman's loose-fitting t-shirt as she bends over.
I don't generally like the way girls look in hockey jerseys, but I do appreciate the increased odds of seeing some ne'er boob when they pet dogs or whatever.

Breasts with an almost supernatural jiggle. Like water wrapped in a thin layer of skin. Not necessarily attached to a fat woman, and more common in physically active women who have jogged the firmness out of their chest pillows. Rippling is noticeable with even the slightest movement. When unsupported, they sag and flatten out to the shape of the ribcage from which they hang.
I saw this chick with a low-cut top and water boobs biking down the street. She was hitting potholes left and right. I couldn't NOT stare.
