Sakura Miko is a Japanese VTuber with Hololive who debuted in 2018 and is known for her high energy streams, playful voice and frequent cute noises. Clips of her sneezing have been shared by fans for years as a running joke about how even small moments become highlights. TSKR grew from Japanese chat slang based on tasukaru, meaning to be saved, and Hololive viewers spam it whenever a streamer does something especially helpful or adorable. This sneeze clip spread through fan clips, chats and soundboards as shorthand for that feeling.
