Definition
Meaning

A humorous, informal, and often childish or affectionate term for one's backside. It implies a certain silliness and is typically used in light-hearted or mildly embarrassing contexts, not in formal or medical settings.
Linguistics
Semantic Notes
Primarily a British term. While anatomically referring to the buttocks/anus, its use carries a strong nuance of playful embarrassment ('get off your jacksie!') or endearment ('fell on his jacksie'). It is not a vulgar or aggressive term like some other slang for the same body part.
