Place it at the reveal, just as the supposedly luxurious item appears, then follow it with Emotional Damage when the flex falls flat. For a drier reaction, use Bruh instead as the immediate reply to the boast.
About this sound
This is a short Spanish voice clip, lasting about two and a half seconds, that names Blue Label de Johnnie Walker in a dramatic, bragging tone. It feels funny and pretentious at once, turning an ordinary moment into a mock display of wealth and status. The delivery makes the premium whisky name land like a punchline, so it works best when the scene it accompanies is clearly far from luxurious.
