It means after a long night of bar hopping,you generally don't care what you eat...Pizza,Tacos, dumpsterd donunts, a live cat...whatever you can get your grimy mits on. You're Drungy,my friend.
Dude, we went to Common Grounds,Durty Nellys, and the Atlantic,and I'm drungry! Let's go to Flacos and eat everything they have left! oooh and some street cart hotdogs too!
Kris was so drungry, while waiting for his sandwich to be made at the deli, he ordered another sandwich because he forgot that he had already ordered a sandwich and couldn't figure out what he was standing around waiting for.
