4/20

The unsimplified version of 1/5 for a bunch of dumb asses who never passed elementary school math and subsequently never learned to reduce fractions.

Person 1: Hey, ready to celebrate 4/20?
Person 2: Actually, I will be celebrating 1/5, since it's the mathematical equivalent to 4/20.
Person 1: ...k...

4/20

The day where a bunch of people go up to parliament hill (or they go anywhere) and smoke pot (weed) because the police can't get them in trouble because so many other people are doing it too! It's basically the one day that yu can smoke pot without getting into trouble...

Hey, it's 4/20, let's skip school and smoke some pot up on Parliment hill! (Ottawa)

Time to get high. Very, very high.

"Later on that there day
My homey, Dr. Dre
came through with a gangk of Tanqueray
And a fat ass J
Of some bubonic chronic that made me choke (shit)
This ain't no joke
I had to back up off of it and sit my cup down
Tanqueray and chronic, yeah I'm fucked up now"-Snoop

There is a belief that it is a code used by the police to describe an offence in progress, saying something like "We have a 4:20 in progress", meaning someone or people are smoking pot. Generally, potheads or stoners will refer to smoking pot at any time as 4:20. 4:20 on April 20th is the ultimate 4:20 of the year.

Hey dude, what time is it? 4:20 man.
(the time could be 9:45, but since they are smoking a joint it is 4:20)
