slack queen (SQ)

A desirable, dignified woman who fulfills the duties of a man's wife/girlfriend while the wife/girlfriend reaps the benefits of her labor. The man seeks/uses the SQ to take up his wife's/girlfriend's slack but is still committed to making sure his wife/girlfriend is cherished on the forefront. Unfortunately, he manipulates the SQ into believing she is just as relevant as his wife/girlfriend who doesn't fulfill his needs consistently. ( other titles: side chick, mistress, other woman, secret lover) ("Slack" refers to limited or no.... cooking, love-making, comforting, or helping with any thing a man may need.)

The CEO called his Slack Queen (SQ) to bring him lunch because his wife didn't feel like coming out in the cold. After lunch, he thanked the Slack Queen (SQ), and then went home to pick his wife up to take her on a trip to Italy.
