Place it at the end of a failed play, just after the death or loss lands, then follow it with a respawn cue to restart the run. A fail sting beforehand can set up the joke, while a dramatic continuation cue works if the story keeps going.
About this sound
This is a short, under-two-second voice clip built around the phrase 'I want to game end myself,' delivered as a flat, self-deprecating gaming reaction. It lands with a mix of frustration and dark humour, the kind of line you reach for after a bad play, a lost match or a moment that makes quitting feel funnier than raging.
