Several areas of South Austin have nicknames that I find rather annoying. My wife, being a native Austinite, finds these geographical monikers to be even more painful on the ears. Some aren't in very wide circulation, fortunately, but somehow I heard of them so I'm including all of them:
SoCo: This one's pretty popular. If you live in Austin, I'm not sure how you would have not heard this one. Refers to the South Congress area which is now populated by kitschy little stores and restaurants, but was formerly a notorious hooker hangout.
SoFi: Not as popular, always heard it pronounced "Soh-f-eye". Refers to South First area.
SoLa: Not popular at all. Refers to the South Lamar area, which is all kinds of busy and nifty and great. There's a store on South Lamar called SoLa that my wife really loves, and I think they were trying to get this nickname to catch on, but alas, I believe they have failed.
Which brings me to my own geographical nickname nomination. I would hereby like to suggest that the entire South Austin area be known henceforth as Saustin, complete with the "sauce" sound and everything. Say it out loud right now, see how it sounds. Try it in a sentence. I live in Saustin. My wife and my dog live in Saustin. Saustin could use a good Indian restaurant. What do people have against Saustin? See? Sounds pretty good.
