Place it as the callout line right after the mistake appears in your edit, then follow it with a bruh reaction for a second beat. For a bigger pile-on, save the emotional damage hit for after this one, not before it.

This short voice clip delivers the Portuguese phrase 'ponto fraco' in a pointed, drawn-out way over about three seconds. It feels teasing and triumphant, like catching someone out on the exact flaw they tried to hide. The clip is tagged to Choque de Cultura from a segment explaining 2001: A Space Odyssey.
