“Look at this dude” has circulated for years as a reaction sound in meme edits, reposts and short videos. It spread because the laugh and the quote are instantly readable even without setup, making it easy to drop onto fails, cursed images and sudden zoom-ins. Creators still use it when they want a light roast instead of a harsh insult. Online, it often appears alongside other classic reaction sounds such as awkward moment or spongebob disappointed in compilations and comedic edits.
