A portmanteau of "cocks" and "proximity," cockximity is the distance between two men and their respective cocks while standing at urinals in a public bathroom.
Toby: Woah, dude, watch your cockximity!
Bryce: I like dudes.
Derived from the combining of English nouncock and the verb to facilitate: the act of helping a friend engage in debauchery or any form or promiscuity with somebody else.
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?"
