The exact origin of this short clip is unclear from the available information, but it fits the style of ultra-brief reaction sounds shared across meme pages, group chats and short-form edits. Sounds like this spread because they are easy to drop into videos without covering dialogue or music. The 'buh' delivery gives creators a fast way to signal failure, confusion or a flat emotional landing. It is often used alongside other blunt reaction audio such as bruh, buzzer-style fails and goofy sound compilations.
