The newest insane TikTok trend is called the "Cha-Cha Challenge." And it has teenagers driving on the WRONG SIDE OF THE ROAD.They play the song"Cha Cha Slide"byDJ Casper. And when he says, "slide to the left," they swerve the car left . . . "slide to the right" they swerve right . . . then both ways when he says "crisscross." It's so dangerous that TikTok has been yanking the videos down. But people are reposting them on other sites.
