Boxing legend Bernard Hopkins says hip hop star Cam'ron must be CRAZY for calling him out in a rap song -- telling TMZ Sports, he'd run a CLINIC all over Cam'ron's face.
Cam'ron -- the guy behind the hits "Oh Boy," "Hey Ma" and "Horse & Carriage" -- put out a new song called "Humphrey" ... in which he says he wants to fight B-Hop and would "f**k him up."
So, when we ran into The Executioner in D.C. yesterday, we had to ask if he thought Cam'ron could take him in a fight.
Ya gotta watch the clip -- B-Hop makes it clear, if the two ever stepped into a ring, Cam'ron would be more humiliated than En'ron.
Here's Cam'ron's original diss track -- **WARNING -- EXPLICIT LANGUAGE**
