A tag team may be made up of wrestlers who normally wrestle in singles competition, but more commonly are made of established teams who wrestle regularly as a unit and have a team name and identity. In most team matches, only one competitor per team is allowed in the ring at a time. This status as the active or legal wrestler may be transferred by physical contact, most commonly a palm-to-palm tag which resembles a high five.
