This clip is commonly used online as a fast disbelief reaction rather than as a sound tied to one clearly documented original source. Short “hell nah” reactions spread widely through meme edits, reposted videos, chat clips and soundboard culture because they communicate rejection in under a second. It remains popular in reaction content for the same reason sounds like bruh and goofy ahh sounds keep circulating: the emotion is obvious, the timing is flexible, and the phrase fits almost any ridiculous visual.
