The awkward amount of breast protruding from beneath a bikini top. It is debatably sexy, but it is def a spring break must.
Wow, That girl on sweet 16 has the under boob thing going on..
Poor Nicole Ritchie, she doesn't have enough body fat to pull off the under boob.

Sometimes an individual is so fat that the rolls of fat on their back become strange, breast-like appendages. They have a bizarre, hypnotic power. Even though you are mildy repulsed, it is hard to look away once you see a real pair of beauties jiggling like there's no tomorrow on someone's back.

Brigid: At least!
2. Jenna: Thank GOD I don't have back boobs!
Cheryl: ...YET!
