"Fixin to" is a neat little southern phrase that indicates an internal process of mental preparation and focusing one takes sometimes just prior to beginning an activity. Esp. when said activity is significantly different in nature or intensity from their current one. In this case, I've just woke up, and will soon begin the final stages of preparation for this years mini-road-trip to DC. So it can be said that I'm fixin to get ready to get my ass on the road.
