Place it near the end of a political clip, after the claim you want to undercut, then follow it with Oh Brother This Guy Stinks for a second dismissive beat before Ba Dum Tss closes the joke.
About this sound
This is an approximately 11-second spoken clip associated with Paulo Kogos, centred on the Brazilian political insult 'petralha' named in its title. The insult gives it a sharp, mocking feeling, suited to taunting an opponent in a heated political exchange rather than making a calm point.
