Here's the FULL 5-minute shot with Floyd Mayweather -- where he blasts Conor McGregor over and over again ... and claims to be the biggest name in MMA.
It all went down on Monday -- when Floyd told our guy comparing Conor to him was "disrespectful" -- because he's an elephant and McGregor is an ant.
There's a lot more in the full clip ... including the part where Floyd accuses Conor of "piggybacking off my name."
Conor responded to part of the video on Tuesday with a message to Floyd -- "SAY IT TO MY FACE."
