A downhill ski race with no rules. Every man (or woman) for themselves, anything goes, first to the bottom wins.
Made (in)famous by comedy movie Hot Dog: the Movie (c.1984)

Get the Chinese downhill mug.
Sex position most used by the Half Mile High club. The girl rides down the mountain on her skis while the guy stands on the backs boning her. When climax is reached, participants fall into the snow to cool off after the steamy encounter.
My winkie got cold when I gave Ronda the old Chinese downhill at the mountain this weekend but it was so worth it.

Get the Chinese Downhill mug.
A phrase used to express lack of understanding when everything should be perfectly clear.

A way of saying "I should understand this completely, but it makes no sense whatsoever."

Origin: In the 1980s ski comedy "Hot Dog: The Movie," the antagonist proposes a Chinese downhill to resolve all conflicts between himself (the hotshot skier) and the protagonist (not so talented skier/cool guy). After they outline what's at stake -the girl, rule over the slopes, cash, etc. -the comic-relief Chinese guy leans in and asks "Wha te fuck is a Chinese downhir?" (A Chinese downhill is a ski race with a shotgun start -first one to the bottom wins.)
Journalists talking about a story that's been assigned, but the second journalist missed the meeting:

J1 -"Good luck getting Pee Wee Herman to discuss his movie theater fetish. You better get on it; deadline is Friday."

J2 -"Pee Wee Herman about what? When did this happen? What the fuck is a Chinese downhill?"
