Examples

“"If there's one Celtic that tries to talk smack to me, it will be Paul (Pierce)," Kobe reported. "We're similar in age, have been through some of the same things, so he feels like he can try. But he's not as good at it as I am. I don't talk trash often, but when I do, I go for the jugular." … "(Today's younger players) don't seem to want to talk any trash," Kobe shrugged. "I say everything to LeBron. He says nothing back. He just laughs. There's no banter back and forth. I guess it's a generational thing. When I first came into the league, the trash talk was downright cutthroat."”
