聖なる手榴弾 アンティオキアの聖なる手榴弾
An explosive from "[[Monty Python]] and the Holy Grail", resembling a [[globus cruciger]].

Alternatively, it can also refer to the explosive weapon in [i]Worms[/i], itself a reference to the above and is essentially a more powerful version of the grenade with a fixed fuse (3 seconds or until rest), a wider AOE and a chanted "Hallelujah!" before explosion.
