PI

Phone Interceptor.

A person who is outside the phone conversation but constantly intercepts by commenting and asking questions in the background.

A constant phone spy. Like the number PI, they keep going and never stop.

IE: girlfriends, sisters and parents
Don't be such a PI. Wait until I get off the phone to fill you in on what's going on.

Can't talk now. I got a PI on my back.
