Place it at the end of the dare setup, just before the attempt begins, then follow it with a reaction sound that answers the dare. A short buzzer can mark a failed attempt, while a second reaction keeps the focus on the person challenged.
About this sound
This is a very short French voice clip, lasting under two seconds, in which a speaker delivers the phrase 'manges tes morts pour le prochain défi' as a blunt dare. It feels confrontational and mocking, with the insult sharpening the challenge rather than softening it. The delivery is direct and unhesitating, making it work as a sudden taunt aimed at someone who has just accepted, or refused, a dare.
