Step Brothers is a 2008 comedy starring Will Ferrell and John C. Reilly as two grown men who become stepbrothers when their single parents marry. Much of the film follows their rivalry, immaturity, and eventual bond, which is why short clips marking their friendship are reused so often in memes and short-form edits. The moment works as shorthand for two unlikely people finally getting along, and its brevity makes it easy to drop into reaction videos, gaming clips, and friendship montages without slowing the edit down.
