side action
Extramarital romantic involvement
Side action refers to a secondary sexual or romantic relationship maintained alongside a primary one—an affair or casual partner kept on the side: He's got a side action he sees when his wife's out of town.
The term is informal and implies secrecy or at least discretion, treating the arrangement as supplementary rather than central.
