A large, pronounced layer of fat under the chin. Similar to a double chin but not anywhere near the girth. Usually found on men, sometimes women. Can be the result of excessive partying/alcohol consumption, over-eating or just being a fat waste. Has a tendency to strike men named Chris during college years.
