Cheating is an act of lying, eception, fraud, trickery, imposture, or imposition. Cheating characteristically is employed to create an unfair advantage, usually in one's own interest, and often at the expense of others. Cheating implies the breaking of rules. The term "cheating" is less applicable to the breaking of laws, as illegal activities are referred to by specific legal terminology such as fraud or corruption. Cheating is a primordial economic act: getting more for less, often used when referring to marital infidelity.
