lady jacket
A woman who’s basically your second skin, but way more flexible and way less polite. You wear her like a jacket, but she’s got more layers.
My lady jacket left me for a guy who wears leather jackets.
He said his lady jacket was the best he ever had, then she left him for a guy who wore a pizza box as a hat.
I told my lady jacket she was my favorite, and she said, ‘That’s sweet, now take me out.’
