The dildometer is a device used to measure the velocity of any given dildo. i.e. the speed of a dildos movement when inserted into an orifice of the users choice.
Tom: What were your new dildo's ratings on the dildometer??
Jessica: My dildo was off the charts!! The dildometer read out the dildocity at an astonishing 100 dildons!
Tom: Wow! You gotta let me borrow that!
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.
