two timing

A form of cheating in a relationship where a person attempts to maintain two seperate relationships at once without one-another involved in each relationship knowing about each other. When information is known, the offender usually openly denies anything's going on, and may accuse one person to the other that the other person involved is either obsessed with a relationship or is a home wrecker and, vice versa to the other person. In typical cheating on the other hand it may be a sexual relationship and, the "on the side" person may or may not know that the person they're having sex with is in a relationship.
