Definition & Meaning of "jailbait"in English

What is the origin of the term "jailbait" and how is it used?

"jailbait" is a slang term that appeared in early 20th-century American English, combining "jail," referencing the legal consequences, with "bait," suggesting temptation, to describe a sexually attractive underage person, usually a girl, whose age makes sexual contact illegal. The term conveys both allure and danger, emphasizing the risk of legal trouble. It has been used in informal speech, popular media, and criminal or cautionary contexts. The term is highly sensitive, context-dependent, and derogatory, as it sexualizes minors; it is never neutral and should be used with extreme caution in discussion or analysis.
