Filian is a VTuber known for chaotic, comedy-driven streams, and short lines like this one are often clipped by fans for reuse outside the original broadcast. Stinky Dayo works because it combines a familiar teasing word with Filian's distinctive delivery, making it instantly recognisable to viewers who follow VTuber content. It has since circulated on soundboards and in meme edits, where creators use it as a quick, friendly roast rather than a serious insult, keeping it popular in gaming and streaming communities.
