Pocket Stalking

A Pocket Stalker is someone who doesn't know how to lock the keypad of a cellphone resulting in huge phone bills and endless voicemail messages with nothing more than the crunchy sound of a pocket.

Bill has been pocket stalking me again all day. Can somebody tell him how to lock his cell?

I'm sorry, I can't go out this weekend. I just received my Phonebill after I have been Pocket Stalking everybody in my speeddail list this month
