| A term used by men to describe their female so's. As in Hey Joe, "I'm goin down to shoot my old lady."
Not necessarily old, but they have to be a lady, or it just gets weird from there.
OR
A descriptor of a woman who's age or looks (or both) have surpassed an arbitrary point when they can be called old. I hope no one calls me an old lady. Especially since I'm a guy. |
