Use it as a quick reaction beat near the start of a short edit, then follow it with a Bruh sound or a Goofy Ahh Sounds clip to extend the reaction. A Meme Instant Sound clip works well just before it when you need a broader meme setup.
Über diesen Sound
This clip is a very short meme sound lasting about a third of a second, centred on a drawn-out mmm hum. It feels playful and a little awkward, like a knowing reaction caught halfway between thinking and laughing. That tiny, exaggerated hum makes it easy to recognise and hard to take seriously.
