Nipple Check 

Process/procedure in which one determines the degree of nipple visibility relative to the ambient temperature, then signals the owner of the nipples in question as to the status of their tit-nipplyness using a two thumbs up/down scale. Thumbs up indicating that their nipples are NOT visible, and vice versa...

Hey, Maya... Nipple check! oooh... Sorry, u fail... (while giving two thumbs down)
