Pop a Flimsy

Otherwise known as a " three way attack ". When you call somebody and have another person on the phone without the person you called knowing.
Your throwed off boyfriend just isn't cuttin' it for you. You love the guy, but you just can't handle it anymore. You tell your best friend to stay on the phone while you break up with him. Most people have a mute button on their phone that they can press to eliminate all sound that escapes from your mouth.
