A passing fad of that is a misnomer for the Hampton Roads region of southeastern Virginia, USA.
It is considered a misnomer because:
1) It does not identify the area in any concrete terms.
2) The name excludes a large portion of the metropolitan area in southeastern Virginia (Williamsburg,
Poquoson,
York County, Northeast North Carolina, Gloucester, Franklin,
Smithfield, Isle of Wight)
3) It doesn't make any sense to say I live in the 7 cities. Really, you live in 7 different places.
You: Yo dude, lets hang in
the 7 cities tonight!
Me: Man,
that word is so 2000. I'm going to
Norfolk.
