I'm pretty sure there is no rule against it, and often times, it leads to more heated exchanges. Only an opinonated dinosaur would take offense to something that would lead to more bitter exchanges in a fight.
Call me crazy but I loved Ali yelling at Terrell, 'Whats my name?' Punishing him at the same time. Great stuff.
lol yes augustus gets warned regardless what he does. trash talking is what leads to the fight 90% of the time so whats the problem with them talking **** while fighting? yes its disrespectful but when your in that ring or in a fight whats the point of showing respect for someone? when you do that you turn hesitant and dont compete like you should. it also could break the focus of the person talking ****. dont wanna start talking **** get cracked in the face then shut up the rest of the fight, itll deff tell your opponent you've changed your mind about what you were gonna do! im all for trash talk but never seem to do it WHILE fighting, guess im more focused on getting the task done rather than talking about getting it done. but you will not miss my commentary after the fight!
