A “coaster” is typically a small, flat object. It can refer to a drink coaster, which is placed under a glass or cup to protect surfaces from water rings or spills. For example, you might put a coaster on a coffee table before setting down your hot cup of coffee.
In the context of amusement parks, a “coaster” often means a roller coaster. This is a thrilling ride with a track that has steep drops, sharp turns, and sometimes inversions. People scream with excitement as they speed along the track of a roller coaster.
