Matt Facer, DJ at League 1 football club Northampton Town, was criticised for playing Last Christmas by Wham at the home game against Portsmouth on 2 December.
As it brings bad luck. And we all love a ridiculous superstion.
“I never knew people took it so seriously,” he said.
Whamageddon started about 10 years ago, and has grown in a popularity through social media.
It now has set rules, a dedicated website and merchandise.
The game’s rules state: “While we can’t stop you from deliberately sending your friends to Whamhalla, the intention is that this is a survival game. Not a Battle Royale.”

Mr Facer, known as DJ Matty, played the song during half-time un the match at Sixfields, attended by 7,215 people.
“I gave it a spin, thinking it would be quite funny to wipe out 7,000 people who couldn’t avoid it, but clearly it isn’t funny,” he said.
“I had a bit of an insult on Twitter, light-hearted, [saying] it was not a nice thing to do, and apparently that was quite tame to what was being said in the stadium.
“So I officially apologise to everybody whose Christmas I’ve ruined.”
He has promised not to play the song during the home game against Fleetwood Town, to avoid upsetting fans of the Lancashire side.
He said “I can take on the chin with my home fans and Portsmouth, but I don’t think I’ll be playing it again.
I think it’s a shame people in professions like mine can’t play Wham! until [late] December, but it’s a game and we all have to jump on board.”
Last Christmas reached number two on its release, finally reaching the top spot on 1 January 2021.
