National Pot smoking day also known as Adolf Hitler's Birthday.

A day that everyone smokes as much weed as they possibly order to keep Adolf Hitler in the Afterlife....forever......thus if you smoke are against the Nazi's.

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

Possibly the best/worst day to have a birthday, in college. Since everyone will be stoned, you'll probably have a 100% of people forgetting it's your birthday, but also an equal chance of getting lit up for free when you remind them.
Birthday dude: hey you know what day it is?!?
Friend: 4/20!!!!!! Time to get baked!
Birthday dude: No asshole... it's my birthday.
*The friend surrenders his bong to the dude with the birthday*
