AKA PTD To constantly trade, purchase, sell and swap one's phone. PTD sufferers are generally underworked, oversexed and have too much time on their hands. The phones of PTD sufferers are always in perfect pristine condition, as one with PTD will constantly clean and wipe the phone after each use (PTDers may also have Germaphobia). Along with being kept in pristine condition, the phones from the PTDer are left feeling unloved and cheap since the PTDer doesn't have the phone in his possession for more than 4-6 weeks. Intervention is critical for the sake of the phone.
