sinbadass 

chris and the other ppl who are way better than him, but he refuses to admit it, even tho his friends come in his room telling him that his music is hawt, but in reality its not that great, because derek is in a coma and can't help collaborate on chris's music to give it that extra zest that it needs to make it huge and the traveling piano pants

Derek and Chris have sinbadass music.

Sirbadasstian 

Sirbadasstian is a nick name for Sebastian.
A Sebastian can be annoying and arrogant with an amazingly huge lack of humility.
Although A Sebastian or Sirbadasstian can be kind and enormous fun when he wants to :)

In General Sirbadasstian is a badass

Sebastian: I need a nick name
Mum: How about Seb?
Sebastian: No mum that's to mainstream, you wouldn't understand...
Sister: how about "Sirbadasstian"
Sebastian: PERFECT
