PSY's "Gangnam Style" dance craze is leaving the confines of the Internet and entering the public sphere — and it's only a matter of time until it invades a mall near you.
The K-pop star brought the trend to our attention Monday night at a Los Angeles Dodgers game, displaying his demented rodeo hop in front of thousands of screaming baseball fans. Now a new video from this weekend has emerged, in which dozens of adoring PSY fans mimic his steps in the aisles of a Pasadena Forever 21. As with any flash mob, some dancers are better than others (dig the spiffy dude in the suit), but the steps are easy and identifiable enough that even the flat-footed get in on the fun. You'd better learn them quickly, America, if you know what's good for you.
