used in conjunction with Azns. A term that describes someone who is a total nerd and is completely full of himself. Usually used as an insult directed at someone who spends to much time playing online games and thinks he's a know-it-all.
Two squirrels chatting online:

Squirrel1: The login server isn't up yet -___-;
Squirrel2: Which means we can't get into the game yet right? o.o
Squirrel1: Well, yea...thats why you can't get into the game. Duh'.
Squirrel1: *Smugly adjusts glasses* That's USUALLY what that means. =.=
Squirrel2: Oh well aren't you just the Nerdasaurus! >.<

Elsie stayed up studying all last night, even though the test is next Tuesday. She is truly a Nerdasaurus Rex.

Someone that is such a nerd that they forced their only friend to call him "galactic emperor" or that he loves ponies but at the same time he created a life sized replica of darth vader than shot him into space in a rocket or that he owns a fan club related to ponies.

He also said "hey i got robux, do you want some." he is a weird person and often calls his
classmates "peasants".
I wouldnt want to sound like a nerdasaurus rex but i want to watch all the episodes of my little pony.
