The line is a playful twist on Mario's famous greeting, a catchphrase Nintendo's plumber has used for decades to announce himself. Usada Pekora, a rabbit-themed VTuber with Hololive, has built a large following with energetic streams, pranks and a mischievous sense of humour, and fan-made edits often borrow her voice for short introductions. The clip spread through Hololive fan communities and meme videos, where its familiar reference makes it instantly recognisable even to viewers who do not follow VTubers. That mix of nostalgia and Pekora's personality keeps it in regular use.
