I was watching videos of car crashes and noted that some were edited with music and audio of the common greeting "Salam Alaikum".
Turns out that someone turned a conversation on Whatsapp (allegedly) into a meme. Then that were posted to Tiktok by user badawi22222 and it went viral.

I can't find statistics due to the common phrase used.
Here is a article describing the challenge and some of its origin.

Alot seems to be locked behind the language barrier. Kan anybody find more info on origins and spread?
