ADOLESCENT SAD SENIOR

When I was just a little boy, my father used to describe worthless individuals as a zero to the left decimal point. An old Worthless Ass.
ADOLESCENT SENIOR has never grown up, still wears diapers, and acts like a small brat who throws temper tantrums when he does not get his way.
Un cero a la izquierda aka Zero to the left. This guy is a double zero on both sides of the decimal point.
