chat-up line(redirected from a chat up line)
A sentence, phrase, or question used to start a flirtatious conversation with a potential romantic or sexual partner. Primarily heard in UK. "Have we met before?" is Ed's favorite chat-up line, even though it has a very low success rate with the ladies. If you hit on girls with that creepy chat-up line, I'm not surprised you keep getting rejected.
