To be completely plastered out of your mind. This word arose from Ireland, where people are usually assumed to be able to drink a lot. Their ability to drink so much came from their sadness over their small genitalia. But, when someone from Ireland lacked any alcohol tolerance, they would be outcast, in quite the same manor the Patriot fans are rejected by society at large. These people were considered nutmegged at the time of their drunkenness.
