C40 

The greatest Northern California DJ you will ever meet in your entire life. Does big things such as party with stars you will only meet if you have the chance to hang out with this great one. Bows to no man for the stature of this man is to great to measure even by the size of the oceans. This music that come out of this mans speaker make lesser men faint and all women wet themselves in matter of minutes at the tantalizing sounds this man puts forth. Lastly, do not try to measure the Swagg of this great one for he does not have any. There is yet to be a word invented for what he is. The closest thing that you can say when you see him is Epic Awesomeness.

Girl #2: No all i felt was the feeling that i was on Ecstasy.
Girl #1: It was Epic Awesomeness!!
