Omelette is used, (as in Lee Nelson's well good show) to encourage peer pressure. If you state that you are going to do something, such as dropping a meaty steamer on your mate's pillow, and another calls 'Omelette', you must adhere to your initial proposition. Failure to do said task will result in the Omeletted individual having to cook a tasty Omelette for the person who called Omelette.
