Spencer Pratt‘s haters — and there are many — are gonna LOVE this clip.
Heidi Montag‘s hubby just earned his brown belt at Paragon Brazilian Jiu-Jitsu in the Valley … which means he’s now a certified badass. He’s one step away from a black belt, after all.
But the former ‘Hills’ star celebrated his martial arts achievement by taking a thrashing from everyone in his dojo … even little kids.
Thank God for this martial arts tradition … and video cameras.
