Slightly Married Woman 

An attractive woman who, although married, gives one of two indications that she is willing or able to be unfaithful to her vows and her current husband. Either she flirts shamelessly with other men in the absence of her husband and displays a great affection for partying, drinking and carousing with other men; or she (while not having any children or is not pregnant) wears an embarrassingly modest wedding ring implying that she would enjoy "trading up" to a more affluant partner.

John: Hey, your friend Jill is quite a little hottie. Too bad she is married. I'd love to give her a ride!
Ellen: No prob. Did you see how she downed those five shots of Jagar that those guys at the bar just bought her? She is only a slightly married woman. Go for it! You'll get lucky before you get to the car!

Jason: Who are you going out with tonight?
Jake: I'm gonna tap this little bette that I met on the bus yesterday.
Jason: I thought you said she was married.
Jake: Dude, with that little pebble of a diamond on her finger? She's only a slightly married woman. I just told her that if she was mine I'd set her up in a sweet Beamer and she'd never have to ride the bus again. She practically blew me right there and then.
