The stage of life at which, no longer nice and open-minded and not yet kind and wise, a human female believes she is prettier and smarter than she really is and deserves more than she's got, and is at her most intolerable. A woman's late twenties are often marked by the beginning or ending of an unwise marriage and a tendency to inflict maximum harm on all around her.
Man: I hear you're seeing someone. How old is she?
Boy: Yes, she's twenty-eight.
Man: Late twenties! You poor SOB. Just remember, whatever happens, it's not your fault.
