Top definition
A noticeably dated or worn model or issue of any object, tool or device that is still heavily used by the owner. A nickname with either affectionate or disgusted overtones for such a device.

Originates from combining the word automobile and the idea that antique machinery often had to be hand-cranked to operate.
Someone smashed my cell phone against a wall, so now I'm back to using the ol' crankmobile.
