Saying 'unbelievable' as a reaction is as old as the word itself, but the exclamation became a staple of internet meme culture as short reaction clips took over forums, YouTube poops and gaming montages. The file's own metadata says it was created in Messenger Plus!, the popular mid-2000s add-on that let MSN Messenger users trade short soundboard clips in chats, which dates this clip to that early era of viral audio sharing. It survived because the sentiment never gets old: every generation of creators rediscovers it for plot twists, fails and fake-outs on TikTok and Twitch.
