The title uses the Korean exclamation 뜨헉, a text version of a startled gasp that appears in chats, captions, and reaction-style posts. Online, short clips like this spread because they are easy to drop into edits when something weird or embarrassing happens. Even without a clearly documented single source, the sound stays useful because it communicates instant shock in under two seconds. It is especially common in meme compilations, anime-adjacent edits, and fast reaction videos where timing matters more than a long punchline.
