Competitive eating is an event wherein participants consume large quantities of foo in a short time period, typically 15 minutes or less, and the eater of the most food receives a prize. The type of food varies, although contests are primarily focused on fast food or dessert. Items are almost always a single type of food, such as hot dogs, pie, or mayonnaise, among many others. Competitive eating is most popular in the USA and Japan. Competitive eaters are sometimes known as "gurgitators".
