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!
