Kinnering is a describing word for just about anything. It can be used in any context, in any situation and for anything.
Are you guys kinnering over there?
I'm feeling pretty kinnering.
Mate, you look kinnering!
Wow, that hat is totally kinnering.
I feel like.. kinnering.
I miss you, you're kinnering!
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?"
