Nate Diaz had a trouble-filled night Friday ... he first chucked a water bottle at reality star Chase DeMoor and then choked a young man into unconsciousness in separate confrontations.
The UFC legend kicked off his wild night by attending the Misfits Boxing 6 event in New Orleans to watch Chris Avilla beat Paul Bamba in the main event.
While Diaz was enjoying the bout in the front row, he got into a heated argument with DeMoor, who was seated behind him. Video shows DeMoor heckling Diaz and calling him a "p...y." Diaz then pitched the water bottle at DeMoor, and the two would have come to blows if onlookers hadn't stepped between them.
