The word "White Trash" is thrown around a lot these days. People usually corollate white trash with being poor. You can actually be white trash and be on any level of the social class; rich, poor, middle class, poverty, whatever. Some people are simply less privileged than others, so they can not be judged by the things they posess.
The definition of White Trash sort of goes along with Jeff Foxworthy's definition of Redneck which is "An extreme abscence of sophistication." That's all white trash is; however, even if one has nice things that person can still be white trash. White Trash people are often times so unsophisticated that they do not even know they are white trash. If one is truly white trash that person is not supposed to know about it.
It is just a coincidence, but many white trash people have bad taste in things. Nascar lovers are often white trash. People who get drunk are often white trash. A drink or a glass of wine are nice every now and then , but getting plastered and shit-faced is just stupid. What's even more white trash than that is saving all of your beer bottles and putting them on the counter. As if they need to be on display. They exhibit other bad habits. They smoke a lot. They have very low grooming standards. The smell bad. They have terrible taste and are badly dressed; tank tops, bandanas, etc...They put their couches on their front porches, and it just looks hideous. They do not take very good care of their kids. They sometimes abuse them or are very negligent. The beat their spouses. Their English is very improper. They also like to curse a lot. They think that saying the "f-word" every other word makes them sound like big people.
What makes people more white trash than anything is their moral judgement however. They take pleasure in hurting others. They are racist. They sleep around a lot and don't even bother to use protection. They date people who do not respect them, or they do not respect their partners. They pick on other people to make themselves feel good. They love to be verbally abusive. They enjoy picking fights, and being rude because it gives them pleasure. Anytime they are nice to other people there is always an alterior motive for some personal gain. They are greedy. They are selfish. Instead of supporting their families they will buy extravegant things for themselves such as a high definition television. White trash people are just bad people. They basically have no social grace, and they feel that the world owes them.

anyone who goes by the name Paris Hilton, wants to be Paris Hilton, knows Paris Hilton, or has spent one night in Paris Hilton.

Slang term for white people that usually live in a trailer park. With low incomes that spend their tax returns on things like big screen TV's instead of clothes for their kids. These people tend to be mouthy and fight frequently. Generally these people are uneducated and have little concern for personal hygiene. To see these people at their best watch Jerry Springer.

A person, or group of persons, who exhibit the following characteristics:

-own more than three yard cars and/or two RVs which must be up on blocks. An extension cord running to the RV is necessary to complete the look. Optional is the standard issue blue tarp covering one or more of the vehicles.

-Huntin' hounds, as many as possible.

-Attack chickens.

-Standard issue Mullet, Nascar shirt(may be substituted with an Stone Cold Steve Austin 3:16 shirt), and acid wash or camofluage pants.

-Unusual fondness for their siblings.

-Still in mourning over Dale Earnhardt.

Some good places to spot these specimens are the local drag races, Costco during food sample time, and DMV.

An individual that may or may not be poor, but is monumentally ignorant and quite possibly stupid.

Someone who is always poor and dirty and some of them are narrow-minded bigots. I really don't like them.
Some more descriptions of them:
-You look next door and see "Muddin" going on and hear country music/Southern rock playing.
-A Rebel flag is flying on the neighbor's porch
-You see hunting dogs caged up in the backyard
-You hear Southern-like Whooping and "hollering" and occasional gunfire
-Your neighbor is wearing Rebel flag attire, is hairy, and is missing so many teeth it looks like his tounge is in jail
-The neighbor is fat, ugly, wears oversized T-shirts and either smokes or drinks a lot, and her hair is nasty looking
-You see duct tape on everything

White trash has nothing to do with money, and nothing to do really with how someone looks. You can be homeless or poor without being white trash, conversely you can live in a mansion and be white trash. See Paris Hilton or Britney Spears. Also white trash love to be in tribute bands for when it comes to art they are at best imitators. See Bon Jovi look alikes. White trash has nothing to do with blood line. You can have white trash parents and not be white trash yourself. You can be a Vanderbilt and have a white trash child. White trash is a mind set and a condition of the heart. The term denotes Anglo-Saxon ancestry but can really apply to anyone who thinks this way.
A white trash person revels in being stupid, is proud of it in fact. A white trash person is never ever wrong and never ever to blame. A white trash person is always the victim and never the perpetrator. A truly white trash person does not even know they are white trash. If you think you are white trash, you are probably not, for that means you have lowliness of mind, a white trash person actually has an monomaniacal Ego. They often will try to imitate others that they feel are intellectual or artistic and emulate what they think are socially desirable traits, however their work will have little soul or substance. Example: I have this friend Avery, she thinks she is an artist because she has the money to afford huge canvases but most of her work is ripped off of or copies of other people's style such as Pica...
