In some team matches, only one entrant from each team may be designated as the "legal" or "active" wrestler at any given moment. Two wrestlers must make physical contact (typically palm-to-palm) in order to transfer this legal status. This is known as a "tag", with the participants "tagging out" and "tagging in". Typically the wrestler who is tagging out has a 5-second count to leave the ring, whereas the one tagging in can enter the ring at any time, resulting in heels legally double-teaming a face.

What does a "tag" entail?
