Place it as the final beat after your evidence montage, letting it close the argument before any reaction. Follow it with the Bruh Sound Effect for a reply, or use the Game Show Buzzer Sound Effect before it when the theory is meant to be wrong.
About this sound
This is a roughly six-second spoken sign-off in a confident, emphatic voice, delivering the line 'But hey, that's just a theory' as a knowing shrug after a long explanation. It feels playful and mock-serious, turning an overconfident guess into a joke that invites the listener to laugh at the reasoning. It comes from MatPat's Game Theory videos, where it closes his detailed breakdowns.
