Aggressive Eating

Eating for the sole purpose of not letting others gain access to any food.

This usually happens to outliers (Weight Wise) in the family, like a human cuckoo bird.

Dude1: "Damn, that fat ass has been eating all of the damn buffalo wings at the party"
Fat ass: "NO ONE ELSE DESERVES THIS FOOD" (Chomps on another 4 wings at once; diverse types of food stains dribbling down his white 4XL shirt"
Dude2: "Fucking aggressive eating, man!"
