JCBSUP, a/k/a "Jesus Christ Built Seattle Under Protest" is a mnemonic allegedly used by taxi drivers to remember the order of Seattle streets in the downtown core, kind of from Pioneer Square up to Belltown. You don't hear it so much now (I'm guessing because everyone has a map in their pocket on their "device." The streets, south to north are: Jefferson-->James-->Cherry-->Columbia-->Marion-->Madison-->Spring--> Seneca-->University-->Union-->Pike-->Pine.
