Psy look-alikes were aplenty at the 2012 HallowMEME costume party on Thursday night -- but only one could be named the gangnam-iest of all.
Attendees were challenged to a "Gangnam Style" dance-off, which was mandatory for anyone dressed as Psy.
The competition was fierce, but photographer Nick McGlynn had the moves (and costume) like none other.
