Something that McDonald's puts on their hamburgers instead of real cheese. Is made out of palm oil and does not really has a flavor but melts very well and is very, very cheap.
Customer; "I would like a nice juicy McHamburger with Cheddar cheese"
Nutritionist; "Actually, that's not cheese. It's substitute cheese. It just looks like cheese"
