Ouro Kronii is a VTuber with Hololive English who debuted in 2021 as a member of Council, and the gwak became one of the small vocal quirks her audience clipped and shared. Fans isolated the short noise from her streams and reused it in fan edits, chat messages and soundboards, where its brevity made it easy to loop or drop into other videos. It remains popular within the Hololive fandom because it captures her deadpan humour in less than a second, and as a recognisable in-joke it signals fandom knowledge instantly among regular viewers.
