The title for my film

I came up with the title for my film after many name choices like unpredictble, My psycho girl friend, twisted, and Revenge of the girl next door. After researching and brainstorming and going through films that have a similar genre to mine i discovered several films with just one word being a descriptive of the film e.g. "psypho" and "Saw". I concluded that my Film title should be one worded as to attract more people and keep some mystery in the title. I chose cheat as people could draw so many conclusions from it and this would get people talking about the film.
