The 'aawow' clip is one of those small meme sounds whose exact origin is hard to pin down; it circulates mainly through user-run soundboards where short reaction clips are collected and replayed. Its spread comes from how easy it is to use: a two-and-a-half-second vocal yelp that reads instantly as surprise or cute excitement, so editors reach for it whenever they need a quick emotional beat. It keeps showing up in gaming highlights, cute animal compilations and livestream sound alerts because it delivers a reaction without words.
