Just finished watching the rest of this video. Derek said something to the effect that he hates all those people on Getbig who don't workout and trash those who do....(like him?). Then he flashed a double biceps pose.
I would guess he suffers from body dysmorphic disorder. Someone should give him a mirror that talks back and doesn't lie to him.
Derek asks, "Mirror, mirror on the wall, who is the best looking muscle dude of all?
"Not you, Derek Anthony" says the mirror, adding, "You look like shit!"
