I like actual promos and they serve the purpose of getting the people more interested in the fighter. Trash talking though is just that - trash. It's moronic to insult the abilities of your opponents. If you say they're "little girls" and can't fight , well if you beat them what have you really achieved? You beat someone you just told everyone was nothing more than a "little girl." If you lose, than you got beat by that "little girl" and that's even worse. A promo should serve the purpose of getting the people to know something about your personality and your philosophy on life in general and fighting specifically. An effective promo serves the purpose of causing the people to make an emotional investment in you. That makes them really care whether you win or lose. They may end up liking you or hating you depending on the reaction you are trying for, but if you do it properly, either way they'll pay to see you fight. They'll either be interested in seeing you fight because they don't like you and are hoping to see someone beat you, or if they like you, they'll pay to see you hopefully win.
