bra snap 

the process of grabbing a girl's bra from behind and pulling it back, causing pressure on the girl's breasts from the bra cups behind pulled back, and releasing quickly, causing a snapping sound. It can be thought as a wedgie of the breasts.

Dan was bored in class, so he gave Danielle a bra snap. She winced as he pulled back, and turned around and slapped him as soon as he let go.

Brasnapping 

Sneaking up behind someone, estimating where their bra strap would be, pulling it and letting go, causing a snapping sound. This causes the person being brasnapped a small amount of pain, surprise, and traumatization (depending on who did it).

Brasnapping random people is quite fun!
