DMV is known nationwide as "The Department Of Motor Vehicles" where you get your tags, licence, ID, and other legal documents with your state.
In the DC Metro Area, it is slang term for the DC metro area. It is a term that has been
recognized as far back as 2004 when local R&B and Hip Hop stations "WKYS 93.9" and "WPGC 95.5" started advertising themselves as radio stations that play the biggest hits in the DC area. As the time has passed by (and thanks to Wale), it has become a widely known term for the DC metro area. There have been local
international calling cards that also bore the name "DMV" as far back as 2000, but never were able to popularize the name for the DC metro area like the way the radio stations did. It is not a popular term in the actual "DMV" area as many people prefer to represent their areas of DC which are: PG, NoVA, Route 1/The Highway (
Richmond Highway portion), Chirilagua/Arlandria, South Arlington, and many smaller communities.
Non Local: "I hear you are from the DMV"
DC Local: "Nahh fool, I'm from the Highway"
Non Local: "What part of the DMV is that?"
DC Local: "I just told you!" "The Highway." "You know?" "
Richmond Highway." "Sacramento Square." "You're slacking!"
Then
of course DMV is self explanatory, unless you live in Maryland, which they call that
government department the MVA.
