During wrapping, we bonded:
Brother: So, the butt dance.My brother doesn't like to talk much.
Me: Oh. That Korean thing?
Brother: Yes. KARA.
Me: Hmm, that's really the only song I know from that group. What's the name of it again? Mister or something?
Brother: No clue. I only know of The Butt Dance.
Me: Oh ... okay.
Me: La la la la lala laa la la la lala la la -
Anyway, this is the butt dance he is referring to. Kinda old news, but I guess no news is too old for guys when it comes to girls doing synchronized booty-shakin':
