I'm like "let's look up some jumpstyle videos on YouTube for the onlookers in this conversation" but I think it's all been deleted out of sheer cringe.
The other dances are also very well executed. I think jumpstyle worked so well as a fad dance is because it's easy to learn, variation is pretty basic, you can somewhat blend in if you can keep a rhythm. Whereas tectonik is fucking awesome but you look like an idiot unless you're crazy good and wayyy confident.
Yeah it was around that time and I am very certain you have the right one in mind. It ended up being the secret "I participated in the Holland exchange" dance in our school and I can still kick it
