This occurs when you give someone your phone number when
You are under the influence (drugs or alcohol). Then you get a call from that person the next day. Now you don't remember what they looked like.
Jane went to the bar and got drunk. She met this guy after drinking way too much. He asked for her number so she gave it to him. The next morning she got a call from this guy who said they were talking last night and he wants to get together. Jane has no idea who this guy is or what he looks like. Jane has been a victim of a coyote phone.
