Nipple Standing 

Standing face to face with another human, with your chest pressed against one another so that your nipples touch.

Also know as, nipple stand

Hey Jennifer, come stand with your chest against mine. "okay, what's the point of this" it's called nipple standing, there is no point but your boobs are really soft.

sand dollar nipples 

Nipples larger than average. In fact, they are at least the size of a sand-dollar. They are acceptable on large breasts, but downright dissappointing on small-tittet women

I took of this girls shirt and she had sand-dollars on her boobs, I thought I was at the beach, even worse she was an A-Cup
