lady night
When a woman drinks wine by herself at night because everyone else is out of the house and she's too lazy to do anything fun. It's basically the opposite of a ladies' night, but way more boring and winey.
My wife had a lady night while I was at the bar with my friends. She drank wine and watched cat videos. I came home to a smug face and a full wine glass.
My mom had a lady night and texted me: 'I'm drinking wine and watching my favorite show. You're on your own tonight.'
My sister had a lady night and posted on Instagram: 'Wine, Netflix, and a very satisfied me.'
