The object is simple but the mission is impossible avoid hearing Wham's ubiquitous 1984 classic, Last Christmas, at any point between the start of December and Christmas Eve
Yep, playing this as always (I fell at the gates of Whamhalla on the 24th last year, when I actually clicked the song-link myself)!
There is an extra bit now; when you have fallen you become a warrior, slaying the song as you welcome in more fallen comrades. Once you have fallen, you get a point for every time you hear the song, so it's not over on 1 December (like it was for a friend of mine).
Be cautious fellow traveller, but if not then fight with honour!
I usually sail through Whammageddon unscathed, but one year, one of my YT subscriptions included a 1 second clip in their video. Did I technically lose? Is there a minimum amount of Wham you have to hear before you are out?
And visiual memes with no audio don't count, right.
