The Houston Rockets 23-point thrashing of the Lakers was NOT the worst L of the night -- that dishonor went to twin bros who got obliterated in a massive nightclub brawl!
We got video of the insanity just as it started Sunday night outside Nightingale in WeHo. Unclear what sparked it, but it's crystal clear about 4 or 5 guys went off on the twins. Fists, feet ... even shoes were used as weapons -- and you clearly hear a chick yell, "I'm gonna cut yo' s**t!"

When security guards broke up one beating, another broke out just across the street.
