Phone Fiddler (PF) is someone who takes your cell phone without permission and changes the background on it, or resets settings, or adds random phone numbers, then returns it without telling you they have just messed with a part of your personal life.
Weena has a tendency of swiping someone's cell phone and with the camera taking random pictures, making one of them the background, then she adds random telephone numbers, then return the cell phone to where she got it, without telling the owner she is the culprit. It's almost like having someone go through your underwear drawer!! What a PF'er. Otherwise known as Phone Fiddler (PF).
