Place it at the end of a setup showing the bad idea, then follow it with Bruh Meme for a second dismissal or Fail Sound Meme when the plan collapses completely.
About this sound
This is a seven-second spoken line delivered in a blunt, fed-up tone, with the speaker flatly refusing to go along with something. The words land as a firm dismissal, and the direct wording makes the refusal feel final. It gives listeners a dry, amused sense of relief, like hearing someone say out loud what everyone else was thinking.
