The line comes from kung fu film dialogue that Wu Tang Clan made famous through sampling, most notably on Da Mystery of Chessboxin from Enter the Wu Tang 36 Chambers.

Online, the short excerpt circulates on its own because the quote and blade sounds work without the full track, turning up in edits about strategy, gaming and combat.
