Place it at the very end of a defeat sequence, after the losing moment has played out. Open the sequence with No God Please No as the failure builds, then let this clip deliver the final taunt, and follow it with Roblox Oof to underline the elimination.
About this sound
This under-ten-second voice clip pairs the Ultrakill boss Minos Prime with the blunt 'rip bozo' taunt, delivered as a sharp reaction. It feels smug and gleefully unsympathetic, turning a dramatic loss into a quick joke for viewers who recognise the reference. It comes from gaming meme edits built around that boss fight and the wider online taunt.
