When something is super fucked up in a redhead or bogan way. The word derived from the legendary redhead, Zachary. His actions have proved beyond "Ahkmedy", forcing us to create a new word for it.
For example, zachary sucked his own dick. That is considered ZACHARISH.
"OMG Zachary, that is so Zacharish"
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?"
