The greeting comes from Obi-Wan Kenobi in Star Wars: Episode III – Revenge of the Sith, released in 2005, where the line became one of the film's most quoted moments. Online creators later paired it with a loud, repetitive woo-woo chant to turn the polite introduction into a joke about over-the-top entrances. The combined clip spread as a meme sound on short-video platforms and soundboards, where it is reused for surprise appearances, parodies and reaction edits. Its lasting appeal comes from that instant recognition: listeners hear the familiar Star Wars greeting first, then the silly chant that follows.
