'Booty Call' Star -- Rips Nick Young's Hair ... The 'Bunz' Look Is Over!!

Swaggy P says he modeled his new 'do after Jamie Foxx in "Booty Call" -- well, now one of the stars of the movie tells TMZ Sports ... IT WAS A HUUUUGE MISTAKE!!!!

We spoke with Tamala Jones -- who played Nikki in the 1997 flick -- and when we told her Lakers star Nick Young decided to twist up his hair to look like Bunz, she straight LAUGHED AT HIM!!

"The 'Bunz' went out in whatever, 2000!!! He cannot do Bunz!"

"Marlon [Wayans] did it. Jamie did it ... IT'S OVER! IT'S DONE!"

Jones is hilarious in the clip ... she's clearly not feelin' it ... but she does give Young one quasi-compliment.
