hyper coster- coaster over 200 ft. tall
giga coaster- coaster over 300 ft. tall
out and back- A type of coaster layout that goes out in one direction, turns around, and then comes back to the station. The "out" and "back" parts are usually parallel to each other. I'll try to post a picture if I can later. Fairly common on wooden coasters. It's one of the older types of track layouts.
