the context of the internet and gaming slang, a “mimic” is a creature or object that disguises itself as something harmless—like a treasure chest, door, or NPC—to lure in and ambush unsuspecting players. [1, 2, 3]

Popularized heavily by the Dark Souls franchise and Dungeons & Dragons, the term has become synonymous with deceptive traps that punish curiosity. [1, 2, 3]
