stuff (one's) face
slang To eat a lot of food, especially quickly and in a short period of time. I have to leave for my four-hour meeting in 15 minutes, and I don't want to be hungry later, so I need to stuff my face real quick before I head out. Sorry, I'm not hungry for dinner—I really stuffed my face at the luncheon earlier.
