Dr Zomboss is the main villain of Plants vs Zombies, the tower-defence game first released by PopCap in 2009, where he appears as the final boss leading the zombie attack on the player's lawn. His short, taunting laugh captures his smug personality in a single sound, which is why clips of it are lifted from gameplay and reused in meme edits. It sits alongside other laughing meme clips as a quick reaction sound, still used because it instantly signals villainous gloating without needing any dialogue or context.
