The line comes from Pittsburgh Steelers head coach Mike Tomlin speaking to reporters, and the short, confident delivery quickly made it a favourite reaction sound among NFL fans online.

Steelers supporters in particular reuse it after wins, during rivalry weeks, and whenever predictions go against them, keeping the clip relevant season after season as a shorthand for unbothered confidence.
