UFC star Luke Rockhold says he got DONE DIRTY on "The Millionaire Matchmaker" -- and was made to look like a scumbag on the show ... but claims it was worth it 'cause he hooked up with one of Patti Stanger's smokin' hot co-stars.
Of course, Rockhold's appearance on the show earlier this year was super controversial -- after he asked one of his potential matches if she "spits or swallows."
Patti tore Luke's ass up in a post-date meeting -- a meeting where Luke can be seen putting the moves on Patti's attractive assistant.
Check out the clip -- Luke makes it seem as though SOMEONE in Patti's office wanted a piece of The Rock ... but he's mum as to which lady got the tongue.
And there's even MORE silver lining ... Luke says his social media pages have been blowing up with chicks who wanna hook up ... and as Luke puts it, "They don't say they spit."
You stay classy, Rockhold.
