I usually just tell them I am responsible for moving data around between files, databases, and devices. If they ask what my company does, I ask them when was the last time they had a pre-employment or random drug test. They generally go away at that point, or shift the conversation to find something less technical to talk about. Go figure. My official corporate title is Business Intelligence Developer, which I, being a fan of Louis La'mour westerns, like to think of as being a Data Cowboy.
