Waapp disgust circulates as a very short meme reaction clip shared on soundboards and in chat apps, where its name comes from the compressed, phone-recorded style of the audio. At just half a second it spread because it can be dropped into almost any edit without interrupting the flow. Creators use it alongside other meme reaction sounds to mark moments that are nasty, awkward or simply wrong. Its popularity comes from speed and clarity: listeners understand the emotion immediately, even without seeing the original context at all.
