Sounds like this spread through user-generated soundboards and short-form meme edits, where very brief clips with an unexpected final word are easy to reuse. The title itself describes the structure, two meows followed by the slur reference, which makes it instantly searchable for creators who have heard it in another video. It belongs to a wider trend of bait-and-switch audio, similar in use to a censor beep for cutting off or masking a line, where the humor depends on timing rather than context or a known original source.
