First, ask yourself these questions:
A. You experienced weightlessness as a result of being flung at 80 mph over a series of small hills.
B. You experienced motion sickness.
C. You experienced being completely disoriented in less than two seconds.
D. All of the above.
2) During a night ride on a stand-up hypercoaster you go through a series of inversions and under a headchopper. What just happened?
A. You rode a 200-foot-high stand-up roller coaster at night.
B. You were turned upside down several times.
C. You went under a bridge and had the sensation that you might be decapitated.
D. All of the above.
If you didn't answer D to both of the above questions, use this list of 20 words and phrases to help understand what may happen to you on your favorite ride.
Airtime: The sensation of weightlessness while riding a coaster. This usually happens when going over a hill or during a drop, and is also known as negative G forces, or coming out of your seat. Apollo's Chariot in Busch Gardens Williamsburg is one of only five coasters in the park, but its 73-mph speed and multiple opportunities for airtime make up for it.
Barrel roll: A complete sideways twist that sends a train into a 360-degree roll, taken from a jet-fighter maneuver. Six Flags America's newest coaster, Storm Runner, features a barrel roll.
Camelback: A series of two or more hills, each one smaller than the last. Paramount's Kings Dominion's Hurler thrills with two camelbacks.
Dark ride: A roller coaster that is completely enclosed, enhancing the sensation of the ride since you can't anticipate its dips and turns. Kings Dominion features the Flight of Fear, an alien-themed dark ride that is sure to scare you out of your skin.
Dead spot: Part of a coaster ride where the train loses all momentum and intensity and just rambles along. Too much of this can ruin a coaster. Often, it exists as a long, straight and flat piece of track. Although the Rebel Yell at Kings Dominion has a few dead spots, these do not ruin the ride -- you need them to catch your breath.
Dog leg: A sharp bend in an otherwise straight track. The Wild One at Six Flags has a number of these turns.
