A booty scoop is a dance move usually involving two people in which the performer squats while placing her hands on her thighs and gracefully rubs her butt up the receiver's pelvic region.
After some sweaty dance floor booty scoopin', I was ready to go back to her place for some real action.
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?"
