I.T. manager Eamonn Kilbride dropped to the floor after aping the energetic horse-riding style moves of Korean pop sensation Psy at a country club in Northern England.
Julie, his wife of 23 years, was with him celebrating her birthday when he began to complain of chest pains.
Despite desperate attempts from his wife and paramedics to revive him, Kilbride was pronounced dead at the scene.
A coroner later ruled that the 46-year-old had suffered from acute heart failure.
Mrs. Kilbride was quick to pay tribute to her "loving husband" who she said lived life with a smile on his face.
"I want people to know how he would help anybody whether it was a life-long friend, or someone he had just met," she told The Sun. "He was a great family man and he worked so hard.
"Eamonn was always the life of the party and loved dancing. We were having a fantastic time at the Christmas party and Eamonn had just finished dancing to Gangnam Style.
"He was up on stage and entertaining everybody. He said he had a bit of a pain and just collapsed.
"I tried to revive him until the ambulance got there, but by the time he got to the hospital he was gone."
Mrs. Kilbride continued: "Eamonn was such an intelligent man, he inspired our children and made sure they had a good education.
"He loved me dearly and would tell people all the time. I know he thought the world of us."
Mr. Kilbride is survived by his wife and three children, Laurajade, 22, Jack, 21, and Conor, 18.
