Place this clip right after the on-screen defeat, not during the fight itself. Lead into it with the Enemy Spotted callout for a setup, then follow it with the Roblox Oof for the failed revenge attempt that comes next in the edit.
Über diesen Sound
A short 3.3-second clip of a young kid yelling 'I'm gonna beat all your asses' in a high, furious voice during play. It feels hilariously overblown and tense at once, because the threat is huge while his voice sounds so young. It comes from an online gaming session where other players were deliberately winding him up.
