The holy hand grenade comes from Worms, the turn-based artillery series by Team17 that began in 1995, where it became one of the most recognisable super weapons. It is a playful nod to Monty Python and the Holy Grail, and its hallelujah chorus borrows the famous refrain from Handel's Messiah. Players loved saving it for a final, match-ending throw, and clips of that cue later spread through gaming videos and soundboards as a shorthand for divine, over-the-top destruction.
