Filthy Frank was the absurdist comedy persona of creator George Miller on YouTube, whose chaotic sketches became a major source of meme audio long after the channel's peak. Yandere, meanwhile, is a Japanese anime and manga archetype for a character whose affection turns possessive and dangerous. The combination caught on in meme edits and soundboards, where a short Frank clip could instantly signal that shift from sweet to sinister. Because that contrast is easy to recognise, the sound remains a handy shorthand for obsessive crushes and jealous reactions in short-form video.
