If a person or animal chomps their way through food or chomps on food, they chew it noisily. On the diet I would chomp my way through breakfast, even though I'm never hungry in the morning I lost a tooth while chomping on a French baguette! to chomp at the bit: see bit = munch. The act or an instance of vigorous biting: "He finished the last of his sandwich with a single chomp" (Anne Tyler). to eat something chomp on (CHAMP)
