pickup truck gomer
A tall, hunched over hayssed yokel type, a simpleton who is basically a doofis, who drives a pickup truck, and thinks he is really cool, although in reality is a total dork.
The Pickup Truck Gomer thought everyone believed he was cool, but instead they all laughed at him behind his back and viewed him as an overly tall, doofis, noodle-head, and simpleton in a stupid pickup truck that he never used for any real pickup truck type work.
