Slang and Lingo

As I have been browsing RPG communities on Lemmy, Facebook, and Reddit, I have noticed some of the slang that I used to hear is not present much in these discussions. Now I know over time, slang and lingo do change, and I want to know more about your experiences in it. One of the terms I used to hear was "fish-malk", referring to players that take on a character to be goofy, silly, and "random". They were usually useless and made playing the game for the rest of the players rather difficult. So what lingo or slang terms are you using in your groups, or terms you just don't hear anymore?
