The clip comes from Shirakami Fubuki, a Japanese VTuber with Hololive, and it circulated online as fans clipped her distinctive sneeze and labelled it TSKR, a playful shorthand tied to the blessing reaction around sneezes. Shared first in fan communities and soundboards, it spread because it was short, instantly recognisable and easy to drop into edits. It remains popular in Hololive fan videos, VTuber reaction compilations and meme shorts, where a single second of Fubuki's voice can signal affection, humour and community in-jokes without needing any explanation.
