obsessive eating
A person who eats so much it looks like they’re trying to fill their face with food. They’re usually the life of the party, but only because they’re too full to leave.
At the pizza party, Sarah ate six slices and still ordered a whole pie. She’s like a food vacuum.
My cousin showed up to the buffet and ate so much, he looked like he was going to explode. And he still wanted seconds.
The guy at the bar ate three burgers, two fries, and a whole cake. He’s not human. He’s a food monster.
