This is a six-second meme clip listed on the soundboard as 8803332605 v_1, a short user-named entry with no other identifying detail in its listing. The number itself is the recognisable hook for anyone who has seen it shared, and the entry is listed for direct play from the soundboard. It works best when the reference is already clear to the listener.
