Place it just after the question lands and before the reply, so the stall becomes the beat. Follow it with Ceeday Huh for a second reaction, or lead into No No Wait Wait when the speaker tries to backtrack.
Sobre este sonido
This short clip is a single drawn-out vocalisation, a man stretching the sound 'euuuuuuuh' as if he has been caught without an answer. It feels awkward, sheepish and deliberately slow, the kind of noise that makes a pause funnier instead of filling it. It works as a quick reaction to confusion, embarrassment or a question nobody wants to answer.
