The exact origin of the gehhh clip is unclear, which is typical of reaction sounds that spread through short-form video rather than a single source. It circulates the same way similar guttural meme vocals do, passed between meme pages and soundboards where clips like faaah and fahhh live side by side, each one a different flavour of exaggerated vocal disgust or shock. Creators reach for gehhh when they want a reaction that feels more nauseated than angry, and its staying power comes from how instantly readable that retching tone is, even with no context at all.
