If a guy calls you 'jail bait' what does that mean?

[Ellie Lindan]

I have never been called this and I have NEVER heard the expression before.
AH OKAY! Is that a compliment of sorts...?

[Weirdo]

You look underage, and he's over 18..
heres some other definitions of the word:

"15 can get you 20." Ever hear of that? heh.

[Shae]

It means you are too young/he is too old.

[Larry E]

It's not a compliment. It means anyone having sex with you over 18 could end up in jail because you are too young.

[yoonndmex3]

It means your young. And it's not a compliment unless the guy is like some pedophile and that's creepy.

[Absolut]

Jail bait is a term for young girls or girls who look too young.

[Mike M]

ur a hottie who is too young to have sex with legally.
