Coastie, or "coasty," (plural: coasties) is a slang term for a young female from the coastal regions of the United States. The term is primarily used in a derogatory sense in Midwest college towns to describe a female who exhibits a unique sense of fashion. Interestingly, the term is frequently applied to females who are not even from the coastal areas of the U.S., but to any girl appearing to fit into the stereotype, even if she is actually from Illinois, Texas, or even England. A coastie's natural inquisitiveness and curiosity are often her only assets. When she asks you if a number is in the millions or billions place, she is really reaching out to you for help, and affirming her subservience to you. Said subservience is disussed further here.
