Nah, I don't buy it. The posted description
above simultaenously claims the following:

1) "Rice Boy" is in no way a comment on the
actual ethnicity of the driver or owner of a
given car.

2) "Rice Boy" is in no way a comment on the
fact that a car is an asian import, because
it applies to all cars, even domestics.

Thus I can't see how substituting a word like
"Cigarillo" or "Shoe" or "Rectangle" could be
any less logical or have any less basis in
reality than the word "Rice" given that, by
the criteria in the definition posted above,
it isn't based on anything. I mean, if it
isn't based on either of those critera, one
could conclude it's just the product of lazy
thinking.

IMHO it either makes no sense, or definitions
like this are symptoms of back-pedalling...

I have a word I use when I see a 4 foot Supra
wing on a Cavalier or Civic DX - "Idiot".
