She stoped giving me head before I cames and she left. All I got was a half-pipe.

This is the origin of the word as far as I know. Two opposing ramps originally used for BMXers, but now used by snow boarders, roller bladers, skateboards and others. See also quarter pipe.
I heard they're building a new half-pipe down at the park this summer. Let's try it out but I'm not down with wearing all of the armor they are going to require.

A term for a skateboard ramp that looks like a U, named a half-pipe because it is essentially half of a full pipe.
