sidepiece
Affair partner, slang
A sidepiece is a romantic or sexual partner outside one's primary relationship—the person someone sees on the side.
The term typically implies secrecy and lack of commitment: He found out he was just her sidepiece.
Separately, a sidepiece is any component attached to the side of something, as the arms of eyeglasses.
