An abbreviation that is widely used in gaming, texting and on Facebook, Twitter, Instagram and elsewhere on the internet, but what does MMO mean in slang?
MMO stands for Massively Multiplayer Online.
MMO is used to refer to an online game, which is capable of supporting large numbers of players simultaneously.
