Colonel Ryszard Kuklinski with Texas A&M cadets
Invented by Ryszard "Crunk King" Kuklinski (the grandson of an infamous Polish Cold War spy of the same name), Crunkczar, which sounds a bit like Polish donk, is a terrifying new genre that makes ravers lose control of their bodies. The drug of choice is a cocktail of carfentanyl, a downer that's approximately 10,000 times more potent than morphine, and Dexedrine, a powerful amphetamine. (Young fans opt for something slightly less harmful: a mixture of Red Bull and sherbert, referred to as "crunk gunk".)
Some people will break both their arms and continue dancing all night as if nothing has happened. Also, numerous cases have been reported of people dancing so fast that their heart gives in and they drop dead on the dancefloor.
At one rave at the end of last year, when the above song was pitched up to +16, three people dropped dead before the track had finished.
