With no single famous scene behind it, the tilde has grown online as a piece of internet shorthand for sarcasm, approximation and playful tone, especially in usernames, coding and chat. Short soundboards collect this kind of symbol sound because it works as audio punctuation, a tiny cue that tells viewers a message is meant to be read with a wink rather than literally. That flexibility keeps it useful across memes, streams and short videos, where a three-second clip can set the tone faster than a caption alone.
