THE WORLD WIDE WEB!
Like those dynamic subdomain websites where you can enter any word you like followed by the domain name into your web browser and see what the website has to say about that word. I can even show you how such websites work:
Just type anything in the form below, preferably something that really grinds your gears, and press enter. Then you share what really grinds your gears with your friends by simply copying the address that appears in the browser's internet address field and paste it to all of your friends by e-mail, chat or whatever means of communication that you use to communicate with your friends. Then you type in the next thing on your list of things that grinds your gears and repeat the process over and over again until you have become what grinds your friends' gears.
Boy, I tell ya, these kind of websites really grinds my gears.
You know what else grinds my gears?
