The western part of Chantilly, VA. Mostly concentrated in Southeastern Loudoun. Because of its more rural feel (compared to Chantilly in Fairfax) of farm land and empty fields on the outskirts of the suburban centers of South Riding and Stoneridge, and its close proximity to Arcola and Aldie, VA, It is given the title of Chantuckey. It is also a great way to distinguish which part of Chantilly you are in when talking to people.
Guy 1 (on the phone): Hey dude, are yall almost here?

Guy 2: Yeah, we are getting pretty close, we're in Chantuckey right now, I'll let you know when we get to the real Chantilly where there are no fields or trees anywhere.
