A condition that occurs when someone is chunky enough, a bra will sink into their back fat forcing unsightly flaps of skin to protrude over their bra strap creating a floppy "boob-like" formation in their shoulder-blade region. This condition is well documented in smaller towns where there are ample supplies of bacon. It has also been known to correlate directly to a FUPA.
That bitch must be trying to counter-balance her Double D breasts with her C Back Boobies.
