DJ Skribble -- Dissed by Vegas Club Again ... You Can't Sue Us For Saying You Suck

DJ Skribble better get used to it ... someone saying he should be playing in a bathroom stall is not grounds for winning a lawsuit -- that's what a famous Las Vegas club is claiming anyway in legal docs.

We broke the story ... Skribble -- aka Scott Ialacci -- sued Chateau Nightclub claiming its managers broke his contract by dumping him as house DJ ... and slandered him by saying he should be spinning in a bathroom.

Now the club's responding in legal docs ... saying the bathroom comment was just one guy's opinion, and can't be proved false since it's just his personal preference.
