The syndrome in which a respectable girl enrolls at a Big Ten university and subsequently becomes an absolute skeezer. This can include single girls, but is typically found in females who enter school with a boyfriend and promptly cheat on and lie to their boyfriends as a result of the Big 10 influence. Once the syndrome occurs it can never be reversed, and the girls become loose for life.

A type of psychological affliction that causes a person to only be able to over-shop at “Big Box” stores where anything under the Sun can be purchased which fuels the compulsive hoarding difficulties the person already struggles with.
I have a close relative who is suffering with Big Box Syndrome and it is a fine disorder indeed when another person has it and you are the lucky recipient of their generosity emanating from their pathetic and uncontrollable overspending!
