Dance Dance Stormtrooper Revolution

Why would a significant number of Korean men dress as Stormtroopers, head out to the streets, and do a dance routine popularized by some Korean girl group called Wonder Girls? I have no idea, but I do know that of all the wacky things I’ve seen people in Stormtroopers costumes do over the years, swaying femininely and grabbing their own asses ranks among the creepiest. Infinite thanks to Stina for the tip.
