don't worry about sneezing; thanks for the cute sneeze
Internet slang used in live streams when a streamer sneezes. The first gloss is a reassuring response to an accidental sneeze; the second is a playful thank-you when the sneeze is perceived as cute.
When the streamer sneezed, I wrote 'kushami tasukaru' in the comments.
Because it was a cute sneeze, the chat filled with 'kushami tasukaru'.
