Roller coaster
By pure definition, a roller coaster is anything that may seem rebellious or appear dangerous when in fact, it's perfectly safe for family fun as long as you're over the height for 48 inches. Using this definition, it can be determined that Linkin Park is the typical example of a roller coaster.

Society's definition of the roller coaster is that it is a form of mass-transit system for small- and medium-sized cities. In principle, it is similar to a bus or monorail, in that passengers pay a small fee to board and be transported elsewhere. With roller coasters, however, passengers are also sent through double-backwards corkscrews, 85-degree death drops, underground tunnel plunges, and triple-twistback loop-the-loops, often at speeds of over 100 miles an hour and with G-forces approaching space shuttle launch (or crash) levels. Many cities are reconsidering the installation of coasters, due to the number of heart attacks, pregnant woman injuries, and scalding-hot-coffee-spill disfigurations, but they're just pussing out.

Roller coasters are also located in theme parks like Disneyland, Six Flags over Somewhere Really Flat and Boring, Fantazyland, Disneyland 2, Duff Gardens, Vekomaland, and Grue Park. The majority of them are made out of steel, and given names like "Smegma" or "Mind Eraser" or "Deathmachine" or "That thing over there". People love to ride them, for the simple reason that prostitution was made illegal. They tend to generate long lines and vomit.
