<unk>  is a behavior that, while generally not a medical problem, in some cases is a symptom of binge eating disorder or bulimia. In more general terms it refers to the persistent consumption of excess food in relation to the energy that the person expends, leading to weight gain and often to obesity. This may be a brief or short term process (many people overindulge generally during festivities or while on holiday) or a longer term process.
