¿QUÉ SIGNIFICA: "A BUN IN THE OVEN"?
A student of mine was recently trying to remember this expression but although they could remember the "oven" part they were not at all sure about the beginning. The reason for this was probably due to the fact that the word "bun" is not commonly known in Spain.
A "bun" is a round type of bread that is soft and can be used to make sandwiches (por cierto, hay un pueblo en Inglaterra que se llama "Sandwich"). Anyway, the meaning of "a bun in the oven" is that someone is pregnant!!! Crazy, I know, but there you go.
Hope that helps!
