Could someone explain where that hand came from?

It's the angle of the photo, I've seen another picture at a different angle with the rest of the arm and the actual girl there.

Yea....

Is he dancing with the girl?

Can we just take a minute to realize that guy is more interested in the phone than in the girl??? O_o

His arm is covering hers! (This took me like an hour)

OKAY. THAT DOES NOT LOOK HEALTHY.

Lol nope not explain nothing
