Let's start sailing the seas of slimebaggery with the most common asshole encounter of our day and age: The Entitled Dick. We see stories about these full-person leaky sphincters on bottom-feeder news sites every day. They are the kids who scream bloody murder when they get a $500 cellphone for Christmas instead of the $550 one, and grow up to be the adults that tell people who help them change a tire to fucking hurry up because they have places to be. It takes a special kind of person to mow down cyclists because they're too busy texting to pay attention to the road, then say they don't give a shit because clearly they're the inconvenienced one, here. The car got scratched and everything! (Perhaps not coincidentally, these people are also pretty much every rich person ever.)
This picture inexplicably brought to you by the search term "entitlement."
While Entitled Dicks do make excellent comedy fodder, in real life they're so grating that most cheese shops file for restraining orders as soon as they roll into town.
With people like this, it's often better to just ignore them until they wander away in search of more evenly fake-tanned people to annoy. However, should someone feel a slight pang of social justice in their black little heart, I guess an alternate way to take care of this shit would be to acquire every piece of nonlethal weaponry you can. Pile up mace, net guns, fart cannons ...
... totally nonlethal giant murder robots ...
