You're so SoWal if parking in Seaside, Rosemary, Grayton, or one if the popular beach accesses is more like a competition sport in the summer, and you actually say "I just scored the BEST parking place" to show off to your friends. Of course you are totally so SoWal by just attempting to park in any of these places during the summer!
You are SUPER so SoWal if you know a few "secret" parking places and don't share their location with anybody.
