When a women has a wet dream and wonders why she actually had an orgasm without stimulation. The only explanation is that she was Sleepbating. Sleepbating implies that the female individual was sexually stimulating herself unbeaknownst to her own consciousness during a rather riviting dream about a sexy ass motherfucker. This can consist of pleasuring yourself with your hands or by rubbing against your sheets.
Desiree: Holy fuck... did i just have sex???... Nah, i must've been Sleepbating again.
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.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
