The line comes from Mortal Kombat, the fighting game series launched in 1992, where Scorpion, the resurrected ninja Hanzo Hasashi, uses it as his spear attack taunt. Voiced in early games by co-creator Ed Boon, it became the franchise's most quoted phrase and spread through arcades, films and online edits. It now sits alongside other iconic game voice lines such as Bomb has been planted and Enemy Spotted as shorthand for an attack starting.
