Jailbait

Jailbait is a word people use when talking about someone who is too young to be in a romantic relationship with an older person. It's often used to describe a young person who looks older than they really are, but who is still too young to legally consent to sex. Think of it like playground rules- you can only play tag with people who are the same age or close to your age. Just because someone looks like they're old enough to play with the big kids doesn't mean it's okay for them to do so. It's important to respect people's boundaries and stick to playing with people your own age.
