Is This Celebrating Falcons Fan Grabbing Her Friend's Dick?

Many of you believe this Falcons fan's grabbing her friend's junk to celebrate a first down by Julio Jones. I'm a little hesitant, though. Watch the guy's face; he doesn't flinch. Wouldn't he at least react in the slightest way if she grabbed his dick? On the other hand, what else could she be grabbing?
