side boob 

n. What is seen when a topless woman (or very fat man) turn far enough to the side to see the breast, but not the nipple. Many movies, in order to keep a PG-13 rating, show only side boob. Braless women who wear sleeveless t-shirts are notorious for side boob.

"My roommate's girlfriend was wearing his muscle shirt without a bra. It was side boob city."
