Nick Carter and his buddy claim they were repeatedly beat down by staffers at a Key West bar -- something they drunkenly tried to tell cops right before they got arrested.
We got the bodycam video shot by a Key West officer outside Hog's Breath Saloon Wednesday night, where Nick and Michael Papayans blurted out their version of the fight.
Papayans admits they were relatively drunk (whatever that means), and that Nick popping off to a bouncer started the fight. Actually, it wasn't much of a fight the way he described it -- "They tackled me like they were f**king Navy SEALS or something."
Cops checked surveillance cams, and as we first reported ... busted both guys for misdemeanor battery.
The vid's kinda dark, but the audio is crystal clear ... especially when Papayans tries to drop Nick's name to the cop, and gets no reaction.
