I could only bring myself to actually watch this once and had to avert my eyes quickly, but I figured many of you would want to see this. The sound of "snap" and the "Oh my God" that comes after, combined with the visual, are too painful to watch over and over. Either way, the second "Battle of the Biceps" is example number 1,257 that straight guys looooove showing off in front of each other. Video after the jump.
