a girl that is attractive but too young to have sex legaly (under the age of consent). she may tempt older men to go after her, and if they do they will end up behind bars....hence, she is "jailbait".

the age of consent is different in different parts of the world. In NY, its 18.

What ugly men in their mid-20's yell at attractive teenage girls from cars. Infact, it happened to me today.
You can't tell if you should take it as a compliment or not.
Most likely you looked it up on here because of that certain situation.
It's referring to a sexually attractive, but under aged girl. You hear it less in Canada since the age of consent is 14.
Guy in car: "JAILBAIT!!!"
You: "What?"
Friends: "I don't know O_o"
You: *looks it up on urbandictionary.com*. OH MY GOD.

1) An underage girl. From the punishment for statutory rape (i.e., consensual sex with a minor or mental defective being considered technically illegal if not in poor taste) being a felony charge that carries prison time.
2) A juvenile delinquent or repeat offender, from their taste for getting into trouble, their constant trips to prison, and the fate of the silly bastards when they get there.
1) The rule with jailbait is that 16 will get you 20.
2) "Jake got sent up for dealing crack to schoolkids again? Man, that dumbass jailbait thrustbucket must like prison food and free orange jumpsuits."

Underage females that usually attract older men twice their age. They say they shave, but in reality, they have yet to hit puberty.
