1. Has a daughter that got knocked up by the son of meth lab owner. (any direct association with meth-amphetamines is a strong white trash indicator).
2. More ignorant of world affairs than the average 7th grade Social Studies student.
3. Despite being remarkably ignorant, does not read, does nothing to rectify it and plays the victim card every time an ass is made out of her in an interview.
4. Gives her children white trash names that will look horrible on their future resumes, sound stupid to anyone else, but have "meaning" to her. (Trig, Bristol, Piper, and Willow). Trig of course being the most unfortunate name.
5. Is a Charismatic Christian. Sure, speaking in tongues, going to churches that "cast out demons", and having various other "spiritual gifts", is not in and of itself always indicate what trash, but when its in conjunction with either characteristics 1, or 2 and 3, its a solid white trash indicator.
6. Has a tanning bed installed in the home as soon as they have the means to do so.
7. Is thin skinned - this is due to inferiority complex common to white trash.
8. Whores out special needs kid at every single opportunity to use to club political opponents with. Basically, its who hates or wants to kill Trig this week.
I could go on, but since all it takes is 4 or more characteristics to denote someone as white trash, you probably get the point.
