Definition of «gm»

“GM” is an abbreviation for “game master,” the person who runs a tabletop role-playing session and controls its setting, challenges, and non-player characters. It is especially common in gaming communities, where the shortened title fits naturally into quick posts, group chats, and campaign updates. The abbreviation assumes an audience familiar with role-playing games, so it can make a complicated adventure problem sound like a routine technical duty. In the sample, the GM is humorously portrayed as battling a computer update instead of managing the fictional adventure.
