The thought that just because you have a large truck (can be any big vehicle such as a lifted truck, jeep or SUV), you can take over the fucking road, don't have to use turn signals and can hang around Sonic for hours on end with your other truck buds. Typically associated with douchebags and other mall crawlers.
