lady thief
A lady thief is a guy who basically takes another guy’s girlfriend like it’s a robbery. He’s usually hot, funny, and has a way of making the original guy look like a chump. This happens when the original guy is off doing something else, like working, being lazy, or just not good in bed.
My friend’s girlfriend ran off with his coworker because he forgot to send her a text for three days.
The guy from my bar took my date because I was too busy drinking and being sad.
My mom’s boyfriend had a lady thief take him out while he was stuck in Germany for six months.
