This sound comes from the opening of All Star by Smash Mouth, released in 1999. The song became even more culturally embedded after its use in Shrek in 2001, and the first lyric turned into a standalone meme online. Short clips of that opening spread across YouTube, Vine-era edits and later TikTok meme compilations because the line is instantly identifiable and easy to interrupt for comedic timing. It is still used as a quick setup for nostalgia jokes, ironic intros and remix edits.
