An older derogatory slang term for a psychiatric hospital or mental asylum, synonymous with 'booby-hatch'. The term reflects the stigmatising language historically used around mental health treatment, framing institutions as places where foolish or 'booby' people were locked away. While the phrase is dated, it still surfaces in vintage writing, old films, and occasionally in retro-flavoured humour, and understanding it requires acknowledging its place in the history of ableist slang.

In old crime novels, threatening to send someone to the booby house was the go-to way to dismiss anyone who seemed too excitable.
Origin: From 'booby' (a fool or simpleton, derived from Spanish 'bobo') combined with 'house'; parallels the older 'booby-hatch' for a psychiatric facility, in use in American English from the early 20th century. Editorial expansion authored on Slangora (model-assisted, hedged).
