This bad country song was set in Missouri and seems to pay a lot of attention to the slut being 18, apparently for reasons of consent to sex? Note that her presence in a bar, even at age 18, is enough to get everyone involved in a pickle, if not a prison, since the legal dringing age is 21. However, as far as consenting to sex, she need only be 17, not 18. See Missouri Revised Statues Chaper 566;
