What??? No, those were definitely two girls. ... I think.
Now that I think about it it coulda been a mirror. the girl(s) looked sad and the thing said "looking for the last-minute hookup" or something to that extent, so the girl coulda been sad looking in the mirror.
I definitely thought they were two girls making out, too, though.
Actually, I just saw it again, and I see how it could be a girl looking in a mirror. It really looked like two girls though.
