Yinaman 

Used to describe a Chinese person or someone from Asian descent.
Comes fromt he word "Chinaman", but is changed to "Yinaman" because it is told that the Chinese pronounce their "CH"'s as "Y"'s
Also describes a horrible driver.
The Worst insult ever, next to Fuad.

Matt: Hey, the guy in front of me is swerving all over the road!
Alex: I know, he is a stupid Yinaman!!
