This entire big slip daddy routine gives me the runs. It only takes a minute to find the lyrics on line. at least half a dozen sites clearly say, "pink slip daddy". Until only recently i never heard of a "big slip daddy". In the 60s we called hem "Posis", not some silly made up term from a misheard lyric. This was SoCal surf, car culture music, not opera. Brian Wilson and the boys probably sat around, smoking some weed and tried to find words and phrases that fit and sounded cool. They weren't hot rodders or surfers, just musicians trying to sell their product Yes, a pink slip is what we Californians call the title, ironically enough because it is pink. Black plates, yellow plates don't mean dick. Just a made up status symbol like YOM plates. Excuse me while I kiss this guy
