look up any word, like cunt:
 
1.
Any object, such as a rock, stick, shoe or butterknife used as an emergency or field-expedient tool. From the old TV series "Then Came Bronson" when Bronson (Michael Parks) uses a rock to pound dents out of his bike's fender and gas tank.
That guy can fix anything with a Bronson rock and a smokewrench
