Not so sure if this wiki knows about this but I'll put it in here anyway...

In certain circles of the Internet, they are taking the Whamaggedon challenge, which is basically not listening to Wham's "Last Christmas". The rules are best explained here below taken from the original cite :

The Rules![]

The First Rule: The objective is to go as long as possible without hearing WHAM's Christmas classic; "Last Christmas".
The Second Rule: The game starts on December 1st, and ends at midnight on December 24th.
Use your local timezone, if you'd like.

(Yes, we're European heathens)

The Third Rule: Only the original version applies. Enjoy the #!€#%!€%€& out of remixes and covers.
The Fourth Rule: You're out as soon as you recognise the song.
Bonus Rule: Post on social media with the #whamageddon hashtag when you get hit.
PvP?: 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. So ... don't be a jerk, mkay?

You know what, I heard the original... in December 11 2019 while I am preparing for my class. So, RIP (#Whamageddon). However, feel free to join the callenge itself, which doesn't had any physical damage except that you will never make it (maybe).

Feel free to comment or announce it in the comments!
