A three-way (MMF) performed in the front seats off a moving car. The female participant lays across both the driver and passenger seats and receives both the driver and passenger (orally and presumeably vaginally) at the same time. The name derives from the fact that only someone of short stature (such as a Chinese person) could successfully pull this maneuver off without knocking out a window.
"Did you hear about Dee, Charlie, and Abraham? They got a wreckless driving ticket for having a Chinese Freeway on the Dallas North Tollway!"
