omelette ass 

A cross between a bubble butt and a flat butt, shaped like a half moon.

I saw this girl in a bar and told her she had the greatest omelette ass I have ever seen...she took me home!

ass omelette

An omelette made by injecting an egg mixture into one's anus, swirling it around, then expelling it into a fry pan. Normally, one eats the omelette with various spices, such as salt and pepper.

"Man, she made him the best ass omelette ever. Chives, spinach, feta, and all."
