A name for a man so extremely hot and sexy that you could bake cookies on his chest, thus using it like a cookie sheet. By the way, this person would be so hot that the cookies would just melt right off.
1. That guy playing basketball over there without his shirt on, ohhhh he's a cookie sheet.
2. The man with the flub hanging over his pants is totally not a cookie sheet!!!
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
