I use a random group of words as variable, etc. names when I can't think of them fast enough to stay in the flow. I find it easy to remember what each one does, and can go back and rename them to more reasonable things before doing a commit. It only takes missing one inexplicably named 'deodorant' variable, for me to want to sink into the depths of the Earth at the thought of people thinking I'm one of these eccentrics.
