UFC badass Miesha Tate says she won't rest until she BREAKS Ronda Rousey's face ... telling TMZ she doesn't just wanna win when they fight -- she wants to knock Ronda's ass out cold.
Tate -- who's currently a coach on Fox Sports 1's "The Ultimate Fighter 18" -- was out in NYC yesterday when she told us how she plans to defeat Rousey when they face off at UFC 168 in December.
"I'm just going to smash her," Tate told us ... "I want her to wake up and see the ceiling and the headlights and me standing over here with the belt on already."
It ain't gonna be easy ... Rousey's undefeated in the world of MMA ... and she's pretty handy with the arm bar.
Still, Tate's confident -- telling us, "I would love nothing more than to break her jaw."
Here's some video of Tate in action -- she's a BEAST!!!
