The word doesn't have much to do with the way you type, neither. It's just simply another way to write/type asian.
It has little to do with culture, although it is more than likely asians will use it (because they are azn/asian?), but it is no different than calling someone asian. It means the same thing -- and it DOES NOT make the person who they are.
immature children who's eyes have not been open to the world who claim "asian pride," usually high school/high school drop outs and under with bleached hair that spend their days at the local arcade playing DDR, also types "LyKe Dis On thE InTerNeTzZzZz"
white guy: you're not white
azn: yO nIgUh?
black guy: you ain't black
azn: got rice?
asian guy: you're not asian
(1) Typing in alternating CAPS and lowercase letters.
(2) Using words such as: dis, dat, sho, da, ETC.
(3) Claiming that Asians are the best even though they don't know shit about their own heritage.
(4) *sigh* I hoped it wouldn't come to this. The dreaded "Got Rice?" song...
2.) Today, commonly used by non-Asians to identify themselves as Asians. This can be contributed to the fact that most self-respecting Asians would not be caught dead doing some of the actions "AzN's" perform on the internet.
They are asian supremecists except that it is not considered to be racist when one is not white (for some reason)
asian: shut up
