Elongated reaction sounds like this one became a staple of meme editing because they stretch a single feeling across an entire clip, giving editors room to build anticipation before a punchline. The long wow works in the same family as other drawn-out exclamations, including a loud yay, and it is often swapped in for a quick gasp when a moment needs to feel bigger. Its popularity comes less from a single viral video and more from its flexibility, since the same sound fits surprise, admiration, disbelief and playful sarcasm across short-form videos, streams and reaction edits.
