When you or your friends start saying it around each other is meaningless. It's when Dad and his friends are totally cool saying it in front of you that you are a proper adult. Still don't say it around the pretty brunette that popped me out of her very often, though. Mom can swear a blue streak if she wants to, as can her sister. The wimminfolk they produced are comfortable with it as well. Doesn't mean I'll break out the UD grade filth I've come up with around them
