This takes a look into the 'who talks more' question. Sadly it will disappoint you if you think it really falls to one sex or the other. There are a few factors, status, formal vs. casual encounters, and how the individual thinks. https://www.theguardian.com/world/2007/oct/01/gender.books Pretty interesting look into things, and shows how the stereo types have been perpetuated for so long.
There was a time when the majority of my friends were men. My personal observation was, and still is, that men trash talk just as much, if not more, than women. I've also come to the conclusion that dealing with men and women is equally as frustrating for reasons that are the same and reasons that are different. I have stories...
Not sure who talks more, but I don't like being around people who go on and on and talk all day. I have someone at work like that and he talks all day, it is hard to get work done.
