PVZ is shorthand for Plants vs Zombies, the tower-defense game in which players use garden plants to stop waves of cartoon zombies from reaching their house. Its cheerful, offbeat style made gameplay clips and reaction edits easy to share, and short sounds from the game became shorthand for an incoming horde or a doomed plan. Because the game remains widely recognised across generations of players, the clip still works instantly in memes, streams and short videos without needing any explanation.
