Put it right after the dubious claim in your timeline, before you cut to your reaction. Follow it with a wrong answer buzzer for a fact-check edit, or lead in with a no no wait wait clip when the backtracking starts early in the scene.

A loud six-second Portuguese vocal clip shouting 'é mentira!', meaning 'it's a lie!', delivered as a blunt call-out. It feels funny and accusatory, perfect for puncturing an exaggerated story in front of everyone. The clip is taken from 'Contexto' by Brazilian band Planet Hemp, as credited in the file tags.
