another one of the many ways of calling someone a noob. Its a spoof of Chicken McNuggets which is a chicken dish created by McDonalds. The phrase Chicken McNublet was first coined by Eric Harvey at a LAN party.
A cross breed between an idiotic person and someone who absolutely cannot do anything right at all. Bad luck follows them wherever they go. Whatever they touch turns to mush. Bring them along and the night will end in sadness. Guaranteed.
There's a party going on and everyone is having the best time ever. All of a sudden this one dude comes in and the cops bust up the party almost immediately.
Person 1: Who invited the Chicken McNubblet?
Person 2: I dunno dude, he always shows up and ruins everything!
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?"
