''You have to meet my parents.''

Why you should never tell this to a girl: Actully, there is nothing wrong with saying that. But for every woman "meeting your parents" is a really big deal. So don't have ''You have to meet my parents.'' becouse it sound like something bad will happen. Instead say ''My parents would like to meet you? Do you want to meet them too?'' So she can be sure that there won't be any problem meeting them.
