stick phone
n.— «Skype bundled its software with SanDisk’s Cruzer Micro and Cruzer Titanium USB Flash drives, which take up about the same amount of space as a stick of gum. The agreement with SanDisk enables Skype users to carry their calling contacts, settings and preferences on the USB devices, which are often called “stick phones.”» —“Skype ‘Sticks’ to Flash” InternetNews.com July 10, 2006.
