They can be found in California, but can also be referred to as 909'ers (reference to the area code).
These people can have a Bar-B-Que and serve SPAM fresh off the que.
They also quite often live in mobile home parks, but may also just periodically LIVE out of an RV trailer (when a job is lost or if the restraining order requires they move).
You: Yeah, but this time I hope he doesn't burn the SPAM. It left black chunks in the tater salad. It was a total Spam-Suckin'-Trailer-Trash mistake!
