Another concert, another couple of girls flailing their arms like odd tropical birds, but the real story here is Mr. Poker Face on the right, trying not to express himself while everything inside him screams, “DANCE! DANCE!”
Also, according to the YouTube description, the guy in front of these girls ended up getting beer spilled all over him. Bonus!
When your dancing is so tight that it bends the curvature of the light around you, you know that you are doing it right. (That or you’ve had one too many beers.)
