One whom is of the white trash community, poor, has no working job, and unpleasant to be around. One may shorten the word derelict to the following words: Darell, Big D, Double D, FORREST,or D approved. It dosen't matter how you say it, it all means the same thing. One may be embarrassed to be around a Darell but face it, we all have a little Darell in us.
Wow dude you just killed the joke Forrest, I mean Derelict!
