When does trash talking work?

A lot of people may consider it unsportsmanlike or even unethical to trash talk, but I believe there can be a positive side to trash talk. It isn’t always antisocial; there can be a prosocial aspect to it, and it can be motivating in some contexts. Michael Jordan used to talk trash to his own teammates to get them to push themselves. Sometimes it can be fun, as opposed to hurtful: My family, friends and I trash talk all the time.
