A man attempting to do the “Gangnam Style” dance–created and made popular by Korean superstar PSY–keeled over and died of a heart attack at his office Christmas party recently.

46-year old Eamonn Kilbride, a former IT manager at his company in the U.K., was celebrating with everyone else when he suddenly collapsed; attempts to revive him failed and he passed away at Royal Blackburn Hospital.

“We were having a fantastic time at the Christmas party and Eamonn had just finished dancing to ‘Gangnam Style,'” his wife, Julie, said.

The energetic dance has become something of a craze here in the U.S. and abroad over the past several months, with PSY earning accolades and fame where he least expected it.
