Use it at the end of a failed attempt, after the setup has made the mistake clear, so it acts as the reaction rather than the setup. Follow it with the Coffin Dance Meme Sound when the fail is final, or lead into it with the Oh No TikTok Song when the disaster is still unfolding.
About this sound
This is one long, throaty groan that drags a defeated 'auughhh' out for roughly nine and a half seconds. It feels embarrassed, annoyed and completely done, like everything has just gone wrong at once. That over-the-top defeat makes it an instant cue for pain, cringe and awkward realisations.
