also: かみころし
noun
deicide; killing a god
Refers to the act of killing a deity, often used in mythological, fantasy, or metaphorical contexts.
その神話では、英雄が神殺しを成し遂げる。
In that myth, the hero accomplishes deicide.
noun
extreme spiciness; killer spice level
Colloquial, often used in food contexts to describe a dish that is overwhelmingly spicy, as if it could 'kill a god'. Common in ramen or curry descriptions.
このラーメンは神殺しと呼ばれるほどの辛さだ。
This ramen is so spicy it's called 'god-killer'.
Compound of 神 (kami, 'god') + 殺し (koroshi, 'killing'), from the verb 殺す (korosu). The reading かみごろし exhibits rendaku (sequential voicing). The slang sense for extreme spiciness is a metaphorical extension.
