In modern days, the word "cheese" is becoming more and more common as an application towards things (usually movies) that are cheesy. Cheesy generally means that something is particularly unbelievable and badly done, put roughly, but the subtleties involved with the word are much more difficult to understand. A good example of cheese would be B movies, such as the Evil Dead line of movies, which are popular as cult classics in many circles just for their cheese. In the movie arena, cheese can generally be easily spotted by bad actors and cliched plots.
Although many people avoid things that contain large amounts of cheese, others are attracted to things by virtue of their very cheesiness. Indeed, cheese and its byproducts are fast becoming popular in this modern world.
