A day in which liberty is taken upon oneself to exclude themself from school or work obligations while, most likely, pretending to be sick or having a death in the family. Usually this time is spent with a significant other (i.e. hookie for nookie
), a sports activity (i.e. golf or playstation), or just plain sitting on ones ass all day editing & writing definintions for modern slang words over the internet. Commonly referred to as "playing hookie".
Dude, the money's great at my new job. But I had to play hookie from work today because I needed the nookie.
