Francis is one of the survivors in Valve's cooperative zombie shooter Left 4 Dead, and his drawn-out scream has become a familiar clip on soundboards and in gaming videos. The sound circulated among Left 4 Dead players who recognised the character's gruff, panic-stricken delivery, and editors later reused it far beyond the game itself. It endures because the scream is instantly readable: no context is needed to understand fear, surprise or comic overreaction, so it works as a quick reaction in horror edits, fail compilations and streams.
