Where is the /dance originated from?

I was checking the mmorpg subreddit and came across a video of characters dancing with almost 100% the same exact dance that Gmod Tower has.

What is the dance animation a reference to? (I really want to know now)

gmod’s current anims were made by maxofs2d, no idea where he referenced his stuff. could just be a common dance.

Have you tried googleing “Generic Dances”/“Famous dances”
