Floyd Mayweather got into a shouting match with a heckler on the streets of NYC on Monday night -- after the fan accused Floyd of running from Gennady Golovkin.
Oh, and the video ends with Floyd's bodyguard threatening to choke a dude out.
Good stuff!!!
It all started after Floyd and his TMT squad left the Knicks game at MSG -- when a very loud fan started screaming at Floyd that he's scared of GGG.
Floyd yelled back to explain why he's not scared ... more yelling ensued.
