When someone's behaviour is so superficial, selfish, difficult to tolerate, and morally reprehensible that the only foreseeable resolution is to sort them out by sodomising them within one inch of permanent rectal damage.
"That Emma is so full of shit, she always interrupts people in meetings."
"You know what she needs?"
"what?"
"dick up the ass."
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?"
