Plural of behind, referring either to the rear parts of things, or used euphemistically to mean buttocks.
From 'behind' (from Old English 'bi' + 'hindan,' meaning 'by the back of'), which is a compound of preposition + adverb. The plural form emerged naturally when referring to multiple things in the back or rear.
Kids find 'behinds' hilarious because we use so many silly words for the same body part—buttocks, bottom, rear, backside, bum, booty—showing how embarrassment around the body creates a whole thesaurus of alternative words!
Euphemism often deployed in diminishing, sexualized contexts directed primarily at women's bodies. Infantilizes and deflects from respectful anatomy language.
In clinical/anatomical contexts, use precise terminology (buttocks, gluteal region). Avoid euphemism that signals shame or sexualization.
