I still don't get the "19". I take it that's slang for something. I've surfed since 15 (1965) starting on a 8'10" Bing at Redondo Beach breakwater, and then on and off with smaller boards, until last Navy times at Ocean Beach and Pacific Beach in the 80's.
I know "toes on the nose"; "cowabunga"; "outsiders"; "tubular"; "line up", and other slang, but never heard that term. But then I didn't hang out much with the hard core culture.
The Corona...19...dude!!
