The art of creeping up to someone while they are sleeping, getting as close to them as possible and then taking a photo of yourself next to them.
Creeping The Sleeping is a great way to ensure that your friends don't sleep in your presence.

Ridiculous or daring poses are preferred.

Is easily performed by insomniacs or those new to instagram.
