Place it right after the bad suggestion in your edit, then follow it with the Bruh sound for a second refusal, or use Emotional Damage first to build up to this rejection.
关于此声音
A short spoken clip lasting under two seconds catches a hesitant voice stumbling through 'Excuse me, um, no' before landing on a firm refusal. The pause makes it feel awkward and politely dismissive at once, like someone trying not to sound rude while shutting something down. That small hesitation is what makes it funny and easy to recognise.
