Portuguese Crow Egg

It's when you shove a Portuguese Crow egg into a girls butthole without breaking it. She then crushes it with her anus and pushes the yok out while you slurp it up with a straw. Originating in the southern farming area of Portugal in the early 19th century.

I couldn't figure out where all my crow eggs were going. Then I caught Amelia with the towns clergymen and a dozen eggs practicing the Portuguese Crow Egg. I filed for divorce yesterday.
