The term refers to the birthday of Bob Marley he was born on April 20 hence 4/20 and shortened to 420. He is the universaly proclaimed leader of the religious use of marajuana.
In Hawaii when 420 is mentioned it is recognized as code for marajuana. The raggae music appreciation and the pot culture is widely recognized here.

420 has nothing to do with waldos whatsoever. 420 stands for April 20th, what is Adolf Hitlers birthday, which many people in the Netherlands(home to amsterdam) and Germany celebrated during Hitlers time by drinking alcohol and, smoking marijuana. The Tradition then made its way over to the United States through word of travelers.

420 was a police code, I believe in a California city, way back in the day. 420 was the code they used for person/people who were smoking marijuana. The term has been used by most every American teenager. Many people use it as a time to smoke. I know of people who consider 4/20 (April 20) a holiday of sorts.
