Place it just after the butter appears in the edit, then follow it with Okay Let's Go to keep the scene moving, or cut to What Da Dog Doin when the reaction needs a second beat.
About this sound
This is a short spoken meme clip built around the line 'This is where all the butter,' linked to Delirious. It runs for about six seconds and keeps the focus on that one odd, drawn-out butter line. The delivery feels silly and light, like an inside joke dropped at exactly the wrong moment, which is why it works as a quick reaction.
