What does TCG mean in slang?

In most contexts, TCG simply means Trading Card Game, and that is how card players and collectors use it. Outside the hobby, TCG occasionally appears as an acronym for unrelated phrases online, but there is no widely accepted slang meaning, and in card communities it always refers to trading card games. If you see TCG in a gaming, collecting, or marketplace context, read it as Trading Card Game. Related shorthand includes CCG, meaning collectible card game, which is roughly the same thing, and singles, which means individual cards sold separately from sealed packs. On EvoMarket, TCG refers to the dozen trading card games we cover, where you can buy and sell individual singles from vetted local game stores and trusted online sellers.
