I would love for Valve to chime in about this since DaFuqBoom is using THEIR IP for his commercial gains, which is 100% against the Steam Subscriber Agreement that Half-Life 2 assets fall under. They should say something soon given recent developments.
Also, pretty sure the original/remix artists who made the song might be a lil pissed too.
Hard to research, because toilet is flooding the search engine results and I'm on Ambien
I first heard a less-electronic (I think original) version over an Instagram reel of a very well-fed Turkish man rhythmically moving his abdomen to the song.
Heard the remix a bit later down the line, still months before the first gmod upload.
