The 'Pizza Meter' is a long-standing theory suggesting that a sudden surge in late-night food deliveries to high-level government buildings, specifically the Pentagon, serves as a leading indicator of an impending military operation or major international crisis. This concept gained renewed viral status on platforms like X and Reddit during periods of high geopolitical tension, where users monitor delivery app activity near Washington D.C. The meme functions as both a genuine OSINT (Open Source Intelligence) observation and a satirical way to signal that secret high-level meetings are taking place, blending humor with global security anxieties.
