A word used a little differently by young Asians, particularly North American asians, who refer to it as the surrounding white culture that is foreign to the comforts of Asian ideals and traditions that they inherit from their Asian parents or Asian peers. Such a word stereotypically refers to what trashy white people are into, and in turn, what asian people are very rarely, if not never, into. This may include skateboarding, driving a pick-up truck, being punk and listening to heavy metal (with black nail polish and chains and doing that hand sign that they do at rock concerts), wearing airwalks, academic incompetence (particularly mathematics), low hygiene, arrogance/lack of manners, laughing at stupid things like a bunch of jackasses over something that is extremely rude in actuality (such as seeing who can burp the loudest), an asian that has an excessive amount of white friends, etc.
Sociological dynamics play an important role within the frequency of the word's usage as it varies depending on what each Asian individual observes, the amount he/she can personally tolerate and ultimately perceive as white culture that is foreign to the comforts of his/her asian cultural values, otherwise ultimately known as white trash.
This is sometimes used in a fun conversation held by Asian friends, without much seriousness and just a little humour, such as poking fun at how almost only white people skateboard and prefer pick-up GMC vehicles. It can as well be used in the form of hatred, more towards those who are rude. This definition is therefore by no means in any form a way to lash at all white people, because many of them are clean, have good hygiene, extremely good manners and are soft-spoken. =)
Turn down that heavy shit man, slipknot or whatever the f*ck you're listening to, i can't stand that white trash.
