Reimu Hakurei is the shrine maiden protagonist of the Touhou Project games, a long-running series known for its large fan community and endless parody content. This clip is a fan-made gross-out meme rather than an official game sound, built around the running joke that Reimu eats too many rice cakes and suffers the consequences. Shared on meme soundboards, it is reused by Touhou fans and editors who want a deliberately crude, unexpected punchline, and its appeal rests on turning a familiar, dignified character into a silly, bodily-humour gag.
