Place it as the final beat after a long, pointless monologue in your edit, not during it. Build false interest first with the Oh My God Wow button, then switch to this clip, and finish with Nelson's Ha-Ha for the group reaction.

A short 3.4-second voice clip of someone flatly saying 'OMG nobody cares,' delivered like a bored dismissal rather than a shout. It gives listeners a mix of secondhand embarrassment and relief, the feeling of a conversation being shut down instantly because the point landed as completely uninteresting to everyone else in the room.
