Serious Sam is a first-person shooter series developed by Croteam, beginning with Serious Sam: The First Encounter in 2001 and built around its hero Sam Stone fighting overwhelming waves of enemies with deliberately over-the-top action and humour. Short audio clips from the games have circulated for years on soundboards and in fan edits, where the most exaggerated shouts are reused as punchlines rather than as serious battle cries. This yell survives because it is instantly recognisable to players and funny even to viewers who have never played the games.
