The ojou-sama laugh is a long-running anime trope, the ohohoho laugh used for wealthy, proud ojou-sama characters, often delivered with a hand raised to the mouth. Amelia Watson, a Hololive English VTuber who debuted in 2020, performed the laugh during her streams, and fans clipped it for sharing out of context. Because the delivery is instantly readable even without knowing Hololive, the clip spread beyond her audience into VTuber edits, reaction videos and meme compilations, where it now signals smug confidence in a few seconds.
