cheater

Cheating is the getting of a reward for ability or finding an easy way out of an unpleasant situation by dishonest means. It is generally used for the breaking of rules to gain unfair advantage in a competitive situation. This broad definition will necessarily include acts of bribery, cronyism, sleaze, nepotism and any situation where individuals are given preference using inappropriate criteria. The rules infringed may be explicit, or they may be from an unwritten code of conduct based on morality, ethics or custom, making the identification of cheating conduct a potentially subjective process. Cheating can refer specifically to marital infidelity. Someone who is known for cheating is referred to as a cheat in British English, and a cheater in American English. A person described as a "cheat" doesn't necessarily cheat all the time, but rather, relies on unfair tactics to the point of acquiring a reputation for it.
