A person who owns every swiffer product and swiffs while on the phone, the computer, watching TV, etc.
Jane managed to swiff her couch, her furniture, her floor, her carpet, all while on her hands-free phone speaking to her mother. By the end of the conversation, her house was swiff clean. She continued on, armed with her swiffer belt which included her hand swiffer, extra refills, and on her back her harnessed swiffer mop walking the neighbourhood for more swiffing opportunities. Along the way she met Joe with the same accessories, another Swifferholic. Soon after they were married and swiffing the world.
n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the internet because it cannot be obtained elsewhere. Not legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the gamealive", so to speak.
Doom II is not abandonware because idstill sells it, while The Incredible Machine is not sold, therefore is abandonware.
