A Luke
A Luke is someone who runs from one fast-food spot to another like a maniac, eating a full meal at each, usually when they're hungover and trying to forget they did something stupid.
Luke: 'I just ate three burgers, two fries, and a milkshake. I'm going to die, but I don't care.'
Luke: 'I went to three different places, and I'm still not full. I'm a monster.'
Luke: 'I'm not even hungry anymore. I'm just doing this because I'm a Luke.'
