Illich (noun) is a term that can be applied to someone who; can't finish or handle their piss, stingy or unnecessarily uptight with money, getting the boys in an unwinnable fight and/or arrested, or embarrassingly bad at spading the ladies.
The phrase is applicable across a range of situations and tones and rolls of the tongue nicely
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?"
