'Platinum' Mike Perry -- a star in the UFC -- punched an elderly man in the face at a Texas restaurant Tuesday night in a violent, angry rage ... and the entire incident was caught on video.
Perry and his GF were leaving Table 82 restaurant in Lubbock, TX while arguing with staffers and other patrons ... and dropping N-bombs in the process.
It doesn't appear the N-word was directed at any black people in the restaurant -- Perry is known to casually throw the word around in daily conversation.
Unclear what set Perry off -- but on his way out, he was accusing another man of "touching" him without permission.
