Kignster,
It is that sort of person that if you call them a name they would get so unbelievably salty they will try to use their whole vocabulary to try and put you down to make them feel better.
Example 1
"Stop being such a kignster"
Example 2
JOHN "Your girlfriends ugly"
SAM "Well, you.. uh. well you eat cock and suck juicy dick, you such a nob, your mums ugly, your girl is so damn fat and ugly that, well your ugly and your life is meaningless.
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.
