Paige VanZant knows not the ways of the evil Cobra Kai ... or how to properly wax a car ... because SHE'S NEVER SEEN 'KARATE KID!'
So, we were talking with Paige about her insane K.O. crane kick to Bec Rawlings' face at "UFC Fight Night" in Vancouver this weekend ... when she dropped the revelation.
"To be competely honest, and I'm gonna be judged as a martial artist, I've never seen 'The Karate Kid,'" Paige said.
"I need to go watch that."
Check out the clip ... Paige also shows off her black eye ... THE SAME BLACK EYE DANIEL LARUSSO HAD AT THE BEGINNING OF THE MOVIE!
"You're the best ... around!"
