Derek is an antagonist. He has a huge ego and is arrogant and cocky...so,what's new?
Bottom line, Derek is a mouth, that being said, he backs up his words with actions.
Derek, is serious. He again puts out an 'open challenge' to all Getbiggers: 'talk smack and i will put you in your place'.
So, to all you shit-talkers out there, Derek will be waiting at his booth!
