(sit-ee gurl) n. A term generally used by delusional, suburban/rural females that have moved to any major city to describe themselves mostly due to the fact that they are ashamed of and/or running away from their past. Its obvious usage is for self-convincing and/or to impress the people they grew-up with in suburbia. Those that use this term are also quick to respond "the city" when asked where they are from. -note: When asking that question and given that answer, it should be quickly followed up with: "Wow, really? Where'd you go to high school?"
