Caller ID

A service most telephone company's offer that displays the calling party's name and number on a display device, which is connected to your phone line.

While having sex with a girl, call her cell phone and when she goes to get it start to masturbate behind her. When she gets to her phone, she'll see its you, look behind her and then you blast her in the face.

The process of calling somone via phone, not reaching them, and, rather than leaving leaving an essentially content-free voicemail message, simply allowing the caller-id feature of the reciever's phone to inform them that you've called. Like phone tag but without burdening the receiver with the hassle of listening to a voicemail message that says "Hi, I called." The process can be repeated indefinitely until the two parties finally reach each other. Process can be foiled if caller-id feature is not available due to poor cell phone signal, phone being off or other service disruptions.

a person so paranoid about revealing their information or identity or being phone screened that they block their caller id so you are almost forced into taking their phone call or ignoring their phone call. Either that or youre getting a call from a bill collector!
