When a nipple (more often than not, the nipple of a woman) slips out of an article of clothing, partially or fully, and is noticed by someone else.

Seriously. Has nobody ever told these brainless celebrity twats that there exists a garment called BRASSIERE? What kinds of exhibitionist morons go around wearing clothes which might reveal a private body part at any given moment, anyway?
