The act of dialling a number, allowing it to ring for just long enough for the person to get their phone in their hand, and then hanging up, forcing them to have to call you back and spend their own money/credit on the call.
A person who constantly, or frequently calls a person without said person's consent, much to the person's dismay. This could be due to the fact that gas prices are going up, that the person is scared to follow you, that the person MUST use all their minutes so they don't expire, or that your voice on the phone just turns 'em on.
"Phonestalker."
"I'M NOT A PHONESTALKER! I ran out of minutes anyway..."
"I'm saved!"
