Bingo cards became a viral meme format because they perfectly categorize shared, often predictable, experiences. From 'Conference Call Bingo' to 'Holiday Family Dinner Bingo,' the format allows users to gamify relatable life situations. While traditional bingo dates back centuries, the meme version gained massive traction on social media platforms like Tumblr and Twitter in the early 2010s as a way to vent about corporate culture or social tropes. It serves as a humorous checklist for expected behaviors, turning mundane or frustrating social interactions into a competitive game of recognizing cliches.
