A person, preferably a female who gives oral sex. A dick sucker. Slang term used around the Chicago area. Could be in reference to Illinois Senator Dick Durbin.

an out of place speck of debris
specifically, a piece of green lint on a white sweater would be a derber. a piece of white lint would not be. a booger on a newspaper would be. a booger in your nose would not be.
