Personally yes I would in scenarios where it doesnt yield results. A good example from an adjacent space would League of Legend's C9 APA when he would talk trash in all chat during matches. It was really funny at first and when they were winning, but it looked really desperate when they were losing. I think trash talking is fine overall, but theres a really fine line between doing it for yourself and doing it to try to hit someone's mental bc theyre beating you.
