Washington Redskins PR -- SHUTS DOWN ESPN REPORTER ... 'No Means No'

"NO MEANS NO!"

Crazy scene at the end of the "Monday Night Football" game last night ... when a Washington Redskins PR guy WENT INSANE on an ESPN Deportes reporter who tried to interview Colt McCoy.

The Redskins QB had just finished up his first postgame interview after leading the team to victory over the Dallas Cowboys ... when the ESPN Deportes reporter grabbed Colt and tried to have a conversation.

That's when Colt's team handler went BERSERK -- getting in the reporter's face, grabbing Colt ... and screaming, "NO MEANS NO!!!"
