Farrah Abraham Fires Shot at Kardashians with a Ray J Assist

Farrah Abraham is ready to take on anyone who wants a piece of her (and not in the porn sense) -- because she fired off a helluva comeback at Kendall Jenner.

Kendall took the opening shot on Wednesday night's debut episode of Khloe Kardashian's show, "Kocktails with Khloe." When Farrah's recent beef with Nicki Minaj came up ... she ripped Farrah for her "decisions in life."

Check it out ... Khloe and co. had some laughs, especially with Snoop's Farrah impersonation. But then Farrah dropped this meme bomb -- a Kardashian/Jenner family pic (vintage with Lamar and Bruce) ... with Ray J photoshopped over them. The caption, giving props to Ray's famous junk, is straight outta the comeback hall of fame.

Which should definitely be a thing.
