jumping castle

A playful, childlike euphemism for sexual intercourse — think of it as the slang equivalent of a knowing wink. The reduplication gives it a deliberately silly, cartoonish quality that softens the subject matter. Used mostly in humorous or self-aware contexts rather than seriously, it's the kind of term you'd use when you want to reference sex without being explicit — in comedy, around mixed company, or when you just want to make someone smile.
