Brittany was ravenous. She wolfed down the salad, then the appetizers, then the entrees, then the dessert, then the horses in the barn, and, finally, the cows in the meadow. She sure was a gold star omnomnomavore.
Person/animal who LOVES food and would whore themselves out for it.
One afternoon, I was passing by a McDonald's when I realized I was hungry, but I didn't have any money to buy food. So I decided to work the street corner to get some dirty money to buy a delicious Big Mac. I'm such a dedicated omnomnomawhore.
