Competitive eating, or speed eating, is an activity in which participants compete against each other to consume large quantities of food in a short time period. Contests are typically less than 15 minutes in length, with the person consuming the most food being declared the winner.

Competitive eaters are sometimes known as "gurgitators," a word used by those close to the sport and an assumed opposite of regurgitation
