The Plants vs. Zombies meme stems from the legendary tower defense game created by PopCap Games, which became a cultural phenomenon upon its release in 2009. The template typically utilizes the game's iconic grid-based lawn layout or its cast of colorful characters to represent the struggle between a protagonist's defenses and an overwhelming force of external pressures. Often associated with the nostalgic 'There is a Zombie on your Lawn' song, the meme has evolved into a versatile metaphor for resilience. It is frequently used to depict situations where a small, organized group (the plants) attempts to fend off a chaotic, never-ending wave of problems or responsibilities (the zombies).
