The Girl That's Always There

When you go to the weed or dope house there is always that one chick that is ALWAYS there. She sleeps with one or more of the "employees" and benefits from their product. Eventually, she will be gone and there will be another Girl That's Always There.

Yes the girl is always right. The guy should know that and not try to argue, especially dont listen to the girls' best friends dad, for he will give you the wrong advice(:

It means that a guy is referencing to a girl who is late for her period, therefore, pregnant.
