3 Cheers for Satan (2019)

It's 1999, and cheerleaders Kenzie Reeves, Kira Noir, and Jane Wilde complain that they're 18 and graduating high school this year. Kenzie casually mentions that she'd sell her soul to look 18 forever and suddenly, in a puff of fire and brimstone, Principal Taylor (Small Hands) appears. But there's something off about him, and it's not just the cloud of infernal smoke... He's actually the DEVIL.
