Saur

Accidental slang for “so” or “super,” often used as an exemplary yet exceeding exclamation in order to show intense surprise or admiration. Is rarely used as a nickname for someone moody or upset, or crazy (as in “dinosaur).

“That is saur cool, bro!”
“Yo, have some patience, man. I know for one that you’re not a John-saur so grow up!”
