The sussy part comes from Among Us slang that spread widely online in 2021, when sus and sussy became shorthand for anyone acting suspicious. This longer what da heeeeeel version builds on the familiar shocked exclamation by dragging out the vowel for comic effect, a style common in soundboard and meme edits. It circulated as a shareable reaction clip rather than a scene from a film or show, and it stays popular because it fits gaming lobbies, impostor accusations and any moment that feels both wrong and funny.
About this sound
A drawn-out voice yelling what the hell in total disbelief, turned into a sussy meme clip people use for shocked and suspicious reaction edits.
This clip takes the simple shocked phrase what the hell and stretches the middle into an absurdly long heeeeeel, said in a loud, incredulous voice that keeps rising with disbelief. The added sussy twist gives it an Among Us flavour, making the reaction feel both suspicious and over the top. It works because the delivery does all the acting: confusion, accusation and comedy land in one drawn out shout. Creators use it when a character, player or friend does something so strange or suspect that a normal reaction would feel far too calm.
