When a guy inserts his penis into a girls tight pussy and fucks her until they both cum, making the guys penis sharp like a pencil. AKA- Sharpening his pencil.
Guy 1- hey how was your girl last night?
Guy 2- great! i was Sharpening The Pencil, if you know what i mean!
Guy 1- ah you're so lucky!
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?"
