who has spewed out more sh1t talking in their careers?

Toney. Can't understand what the **** he says, but it sounds like trash talk.

Audley Harrison by Far.

Ali, but he backed it up.

Ali was playful with his trash-talking... I'd call that "banter" Mayweather is just annoying. Just the sound of his voice is like white-hot needles piercing my ear drums. He never quite figured out how to come off as playful, like Ali did. Mayweather just made himself a target for a hate crime.... and burglary obviously! i doubt frazier would agree w/ you to call that 'banter'. he really was affected by it and hated ali for the longest time. but lol at your avatar, when was that?

Ali definitly However, Mayorga is the king of below the belt comments. Mayorga talks the most shit, does the least backing up.
