Clash Royale is a mobile strategy game by Supercell in which players battle with collectible cards, and the Princess is one of its long-range archer cards. In-game emotes let players react during matches without typing, and the yawning emote became a favourite way to signal boredom or disdain for an opponent's slow play. Clips of game emotes later spread on soundboards and in short-form edits, where the sound works even for viewers who do not play the game because the yawn itself is universally understood.
