Ric Flair is firing back at Conor McGregor ... blasting the UFC star after McGregor proclaimed that most WWE wrestler are "messed up p**sies."
"Coming from a guy who built a career copying my persona, I expected the type of class we get from Ronda or Anderson," Flair posted on Twitter.
"After Diaz finishes you again, I dare you to try guys like Dolph, Brock, or Fit. Oh you're welcome for your gimmick."
"If anyone doubts whether or not [Dolph Ziggler] could tie Conor in a knot, do yourself a favor and Google his accomplishments.
