This sound comes from the startup audio associated with Clash Royale, the mobile game by Supercell. The version here is edited with strong bass boost, a common remix style used across short meme videos and gaming clips. It spread because the original intro is instantly recognizable to many mobile players, and the added low end makes even a simple phone screen recording feel huge. Creators still use it for ironic hype, nostalgic game references and fast edits built around app openings or menu screens.
