Place it after the confusing moment itself, not before it, so the edit reads as a response. Follow it with the Bruh Soundboard Button for a deadpan reaction, or precede it with the Meme Instant Sound Button to set up a rapid meme sequence in a compilation.
このサウンドについて
Popelumut is a 13.7-second clip named for a single nonsense word with an exclamation point in its original title. It gives listeners a deliberately absurd, silly feeling, the kind of random interruption that lands because it makes no sense in context and offers no explanation for why it appeared in the conversation at all.
