The title combines the name Gwen with the Portuguese word horrível, meaning horrible, which explains why the clip circulates with that spelling in game and meme communities. Short named reaction sounds like this spread through soundboards and short video edits because they are easy to recognise, loop and reuse out of context. Rather than being tied to one long scene, its popularity comes from how quickly it signals horror and disbelief, so creators keep borrowing it for new characters, fails and edits where an exaggerated frightened reaction is needed instantly.
