A side girl you frequently get mostly blow jobs from, that your friends and especially your family don't know about. A generally slutty girl, desperate for attention and acceptance, but will never get it. A yopper.
"Yo! I'm gunna go and hang out this my suck me up girl real quick, but I'll hit you up after. It shouldn't take too long."
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?"
