The process of removing yourself from a funky environment and relocating to a sterile, unfunky one. This process should be done gradually and is similar to the process of decompression that divers must undergo to avoid the bends. In other words: once you get that funk in your trunk, you can't just wake up and dump it out like junk.
I've been staying in New Orleans for a long while, but now it's time to move on to Portland. I need a little defunkification in Memphis before I go though, otherwise I'll end up with a case of acute afunkitis.
