In internet slang, gaming culture, and social media shorthand, MTG stands almost exclusively for Magic: The Gathering, the pioneering collectible card game created by Richard Garfield. Depending on the digital context or online community space, the acronym can occasionally be repurposed to reference completely unrelated terms, such as Marjory Taylor Greene in political discourse or specific technical jargon, but gaming circles overwhelmingly recognize it as the ultimate abbreviation for the card game.
