There is no documented source work behind this clip, and with only a handful of views it reads as a personal upload rather than a viral meme. That is typical of name-based diss sounds, which usually start as inside jokes recorded for one friend group and end up on a public soundboard by accident or for safekeeping. It has not spread widely, but clips like this keep getting used because a taunt with a real name attached feels funnier and more personal than a generic insult, especially in chats where everyone knows the Finn in question.
