A small, husky Asian. Derives from the old Mongol term, "Yurdan Ooi" which denoted the lowest-ranking associate of the military, the lad who would shovel the horse defecation and was sometimes condemned to eat it for the entertainment of the warlords. Literally translates to: "Invisible dick"
Haggai: Hey, did you see that Asian guy over there hitting on the high-school freshman chick?

Ryan: Yeah, that guy is short enough that she probably can't tell he is in college. What an Ooi!
