Area code for those inside the Atlanta city limits; Person living "inside the perimeter," as it were, as opposed to 770, the metro area code, for the suburbs... Also a term of pride tossed about casually when representin' the ATL.
Is she 404 or 770?
404, A-Town all da way.

Error returned when a server cannot find the requested page.
Once upon a midnight dreary, while I websurfed, weak and weary,

Over many a strange and spurious website of 'hot chicks galore',

While I clicked my fav'rite bookmark, suddenly there came a warning,

And my heart was filled with mourning, mourning for my dear amour.

"'Tis not possible," I muttered, "give me back my cheap hardcore!"

Quoth the server, "404".

What's up with this new character limit thing, anyway? It pisses me off.

I got the 404 error also!
