halfpipe

HAF-pyp /ˈhæf.paɪp/
nounB1
neutraltechnical

A U-shaped ramp or snow structure used in gravity sports to perform tricks as the rider moves back and forth between the opposing vertical walls.

A halfpipe consists of two flat vertical walls (transitions) facing each other, joined by a flat bottom, allowing riders to gain momentum and launch into the air.

The story behind the word. The term was coined by skateboarders in the mid-1970s. When they cut a large concrete or wooden pipe in half lengthwise, they realized the resulting U-shape was the perfect structure for continuous, gravity-defying riding.
