Can't think of a time when he didn't....
Ali had been trashtalking opponents since he was a amateur boxer in the golden gloves
He's began trashtalking even when he was an amateur fighting in the golden gloves though his trashtalking then was always good-natured and funny.
His very first pro fight against Tunney Hunsaker a sheriff . He trash talked him as a bum.......First pro fight and he's already calling opponents, bums.
and the first opponent he talk trash?
