Snoop Dogg is going OFF on Donald Sterling ... blasting the L.A. Clippers owner for being a "racist piece of s**t" ... and it's all on video.
Snoop unloaded first thing this morning when he heard the audio posted by TMZ Sports for the first time -- dropping so many cuss words at Sterling ... that Richard Pryor would be proud.
Check out the clip ... Snoop calls Sterling "bitch-ass redneck, white bread, chicken s**t mother f***er."
But you gotta watch to fully grasp Snoop's outrage.
