This voice line comes from League of Legends and was clipped from in-game champion dialogue into a short standalone meme sound. Its short length and clear delivery made it easy to lift for edits, streams and soundboards, where it spread as a reaction for unhinged behaviour rather than for gameplay itself. Players and creators reuse it when someone leans into a bad idea with total confidence, turning a throwaway joke about a doctor's note into a shorthand for proudly losing control in a funny, harmless way.
