n00bissaur
A noob so bad they're a monster. They don't know how to talk to people and think they're the best at everything. They wear a backpack like it's a trophy.
My friend's brother is a n00bissaur. He tried to beat me at chess with his hands tied behind his back.
I saw a n00bissaur in the grocery store. He was arguing with the self-checkout machine about the meaning of life.
My teacher called me a n00bissaur because I spilled my juice on my laptop.
