When feeling ill and preparing breakfast, usually after a night of heavy drinking, one vomits into the pan in which they are cooking. Thus, a vomelette is created.
Note: Eggs do not necessarily have to be the food being prepared.

lil mad is like big mad but the opposite, you mad but not mad to the extent of pullin somthin

When the omelette on your plate is so thin and looks so greasy and disgusting with the veggies, meat and cheese flopping out all over the plate that it just looks like a big pile of vomit
