Tina Whore. Generally applies to crystal-meth (aka Tina) addicts who usually do not own their own supply of drugs, but are professional at playing the role of a newbie to partying or they'd simply say/tell/promise you what you want in order to use your drugs. When the drug is gone, so will the TW's...leaving unfulfilled promises.
1. She's such a TW, she'd say and do anything to use your drugs.
2. She's changed and gave her chat profile a fresh look. Different kimono but same TW.
