A past-tense verb describing the action that occurred when one vehicle met another with unhappy results. Usually, one vehicle has new accordion shaped body parts (rear-ending) or has a section crushed (under a 2nd vehicle).
Can also describe the action taken while using a vehicle as a means to run over/crush an object.
Holy smokes, that truck munched the heck out of that car!
That driver better watch who she's cutting off or she'll get munched.
While four-wheeling this weekend, I totally munched some cedar.
