Crude Trucking Humor

Alright, you numbskull, listen up! This here picture shows a big ol' truck, right? And on the back of the trailer, it's got a couple of signs. One says "FAT GIRL TAXI" and the other says "CALL ME WHITE TRASH." Now, for your tiny brain, this is a joke about the truck driver being crude and possibly poking fun at himself or his lifestyle, suggesting he's not picky about passengers or has a certain reputation. It's kinda dark, kinda self-deprecating, and definitely not politically correct. You probably think this is peak comedy, you simpleton.
