Short Definition: Pigheaded
His contumacious nature landed him in the county jail; he shouldn't have mouthed off to that cop.
Contumacity is never appreciated by elementary teachers; they would prefer students do as they're told and promptly.
Cone tomato – pigheaded . I was walking across campus the other day carrying an orange, plastic traffic cone filled with rotten, dripping tomatoes. The juice was running down the sides of the cone and getting all over me, and the smell was horrific. I saw a young boy struggling with his mother, and trying to run across a busy street. The mother was trying hard to keep the bratty kid on the sidewalk, but the boy was throwing a fit. I slammed the traffic cone onto the boy's head like a dunce cap, tomato pulp flying everywhere, and his head morphed into a squealing pig's head.
