An individual who is so clueless, reckless,
stupid, or careless, that it's only a matter of time before they cause
serious harm to themselves or someone around them.
Whenever you see a Toyota Corolla with it's back bumper taped together with duck tape
pressed on half ass, and the
front bumper
straight up gone, it's a pretty safe bet that they're a ticking time bomb and they're a terrible driver who needs to be avoided at all costs.
