Place it as the closing beat after a doubtful claim, then follow with the Bruh Sound Effect for a second wave of disbelief, or open with the Game Show Buzzer Sound Effect before it to frame the claim as already wrong.
About this sound
This 12-second German voice clip opens with a drawn-out 'mhmm' before the speaker says 'weiß ich nicht, digga,' meaning 'I don't know, bro.' The relaxed, unhurried delivery sounds skeptical and mildly dismissive, turning simple uncertainty into a dry, comic shrug. It feels like a polite refusal to be convinced, rather than an argument.
