Place this clip directly after the request or bad idea in your edit, then follow it with a bruh soundboard button as the second beat. If the moment needs a bigger payoff, finish instead with an emotional damage sound button and cut straight to the next scene.
このサウンドについて
This is a very short voice clip, just over a second long, of Sebastian delivering a flat 'nuh uh' in a calm, unbothered tone. The delivery turns a simple refusal into a deadpan joke, giving listeners that smug, dismissive feeling of shutting down a bad idea or request without any extra explanation needed at all.
