Just so everybody is clear this is how 4/20 actually started.
4:20 was the time of day some stoners at San Rafael High in Northern California (represent) would get together every day after school to smoke weed and get high. It is now a huge part of our culture, basically the word for the "weed culture."
It's also a holiday, April 20th, (coming up!) and the only place to be at 4:20 on 4/20 is Hippie Hill in San Francisco.
hey dude look, it's 4:20, take a hit!
shit, what are you doing on 4/20? GETTING HIGH OF COURSE
