Meta
Metagame
Gamers use meta as an abbreviation for metagame. You're most likely to see this term pop up on gaming forums and in Twitch chat, as gamers discuss the state of a game's items, mechanics, and strategies - and how those factors influence their pre- and in-game decisions.
What is a metagame?
A metagame is often described as "the game outside a game" or "the game of playing a game." Those who metagame analyze a game's existing environment and strategies and then devise ways to counter those strategies, to give themselves a better chance to win. Typically, other players then devise counterstrategies for the counterstrategies, producing an ever-evolving metagame.
Gamers may also refer to a game's current established set of "best" strategies as "the metagame" or "the meta." For example, a Magic: The Gathering player may say "the meta's all aggro decks right now." In this case, the player means that all the current best-performing MTG decks, collectively referred to as "the meta," are aggressive decks.
Example
Take the pop culture acronym challenge
Meta is when something, often a piece of art, refers back to itself. For example, a TV show about producing a TV show is meta.
The term comes from the Greek meaning of meta, which is "beyond" or "after." It's often attached to words to give them new meaning, like "metaphysics" and "metadata," but in the 2010s, the usage of the word evolved in pop culture to describe works of art, such as movies or books, that displayed an acute self-awareness of their medium.
Some examples of popular meta TV shows
While people mainly use it to describe works in pop culture, others may use it whenever anything comes full circle in a mind-blowing way. For example, you might think it's meta when you find out your grandmother held the same job in the same city you work in now.
