A married woman who forgoes sexual intimacy with her spouse for no particular reason, although both parties are somehow satisfied with the arrangement

Used by those on the outside looking in as a way to poke fun at such a bizarre state of affairs

Kevin: "I know Woodrow is married and all, but he's always come across as a virgin to me."

Tanner: "Oh, I'll bet my left nut's tumor he is. His wife's practically an indentured escort."

Kevin: "Yeah. What better way to consummate the marriage than to remain celibate indefinitely, am I right?"
