In my boyfriend's house, the word "cush-it" is constantly used when we are being called for dinner.
However, in my Russian-English dictionary I cannot find such a word.

I found that
eat = есть
food = пища
dinner = обед

Where does "cush-it" come from, and what is it's proper meaning?
(To me, I always think that it should mean "cook". I think I am taking that from the Italian word "cucina" [pronounced cu-cheena] which means "kitchen".)

Thank you.
