Every american boxing fan 'It could have gone either say' Said after every fight where an american has won by blind robbery
"I don't have alot to say, I let my fists do the talking in the ring. Tune in Saturday night, it's going to be a war" Then on Saturday night you tune-in and they just jabbing and grabbing and backpedaling the whole fight.
Not exactly a saying per se though it is communicating... I personally hate it when a boxer lands a hard shot and the other guy shakes his as if to say "That didn't hurt"
