The modern version of Hillbillies. It is an endangered species, relegated to the less prosperous trailer parks. Less respected than those who live in "The Projects", but not by much. The republicans think they can legislate all of them away by shutting off all entitlement programs, but will only manage to turn the more resourceful into bridge trolls and bush drinkers and others who wave friendly signs at drivers from the entrance to shopping malls and highways.
It's a derogatory term for people who live in trailers who happen to be poor, perhaps in poor health and/or with no or little insurance. It doesn't mean they have no or low morals, just that they are poor.
It is a derogatory stereotype given to people who are living in not very glamerous static caravan parks. It basically implies that they are poor in money, diet and prehaps health. It is however an assupmtion, as I expect that there are many walks of life rich and poor as there are all over the world. It was originally a USA term, however it is used in England also now, too
A lot of senior citizens live in trailer parks. Are these people uneducated? Do they lack morals or have no motivation? I think not, I agree with KK trainor. I'm sorry that your answer was "hidden due to negative feedback. The liberals must have voted it down.
