Shmoonism

An adjective used to describe the act of spending your parent's money or entire paycheck on anything you don't need in a matter of two days or less, typically a weekend. Another example of this would include spending any and all money that should be used for bills at a bar, or even multiple bars. Generally, most money would be spent on bottles of Coors Light and multiple packs of Marlboro Lights. Also, to be a "schmoon" move, the person has to lie about where they spent/got all their money.
