Usage: Use "fridge" as slang for killing off an unlikable female character in fiction, but avoid it when referring to the literal act of cooling food. This informal term is common among writers and fans discussing plot devices rather than household chores.
The word fridge began as a shortened form of refrigerator, possibly inspired by the Frigidaire brand name before its spelling was adjusted to match words like bridge and ridge. While it originally referred only to an appliance for keeping food cool, slang usage later emerged in fandoms alluding to comic book tropes about female characters being harmed or killed.
