Never start an argument with an ignorant bastard who thinks his business parking in the middle of the road for several minutes during rush hour is far more imperative than the flow of traffic. Obviously, this man already knows his time is more valuable than the rest of society.
So what were you thinking, you saggy piece of harlot, when you stepped out of your SUV yelling "move you motherfucking motherfucker" while your child cried in the backseat? Did you think that the straight up gangsta hermano in the pock-marked Chevy Lumina was going to apologize with sincerity, pull up his pants and promptly shift his car out of everyone's way?
It never occurred to you that he would stride out of his car, leaving the door wide open, pimpwalk over to your dumb ass and make that cocked-elbow busta finger-gun gesture over your greasy head, while his children sat in the back seat of his Chevy. It never occurred to you that there were like nineteen other fucking cars behind you, and waiting would take less time than starting shit.
So I just sat there in front of the elementary school and watched all the little kids crowd onto the sidewalk to watch you fight, while you waved your arms in the air and I could almost smell the pit-stains on your shirt, and it's fucking twenty degrees outside how are you sweating right now?
And you, Mr. Compensating For Semi-Dwarfism With Giant Embroidered Black Pants And A Big Fat Mustache, get your goddamn children out of your car and into that playground before I take them away from you. Next time you want to give your kids a pep-talk before school, remember this: if you keep on instilling them with your current family values (that it's more important for you to prove your manhood to a strange, dirty old white lady instead of going to school), they're going to get themselves shot faster than you can say "please don't shoot my illiterate children."
Oh, but my favorite part was when the Aryan Nation suit-and-tie dicknose behind me got out of his sedan to yell at the two of you for being inappropriate, because adding another stereotypical self-important jackass to the argument will really, really speed things along, and is an excellent example of adulthood for the children loitering twenty feet away.
