Conor McGregor just UNLOADED on Eddie Alvarez at the UFC 205 press conference at Madison Square Garden … telling Alvarez to “suck these big Irish balls.”
It was insane … Conor walked onstage 15 minutes late rockin’ a mink coat … and proceeded to verbally attack Alvarez.
At one point, McGregor snatched Alvarez’s belt off the table … almost coming to blows before Dana stepped in.
If the presser’s any indication of how the fight’s gonna go down … there’s gonna be fireworks Saturday night at MSG.
