I can't believe it's not butter!

A butter substitute made of vegetal oils and frequently used as a spread. Sometimes its name is used as a humorous/sarcastic reference to a sub-par substitute to something.

<Eats a piece of toast>
- Just a moment, is it butter?
- No, it is "I can't believe it's not butter!"
- Well, *I* can believe it is not butter.
