4/20 

a TIME in the 70's where a group of teens would gather after school got out to smoke marijuana. 4:20 was the perfect time because it was after school, enough time to get the weed and smoke before parents got home. since then april 20th has become a "holiday" in which people celebrate smoking marijuana! also, 420 is NOT a police number and they do NOT say that when they see people doing drugs.

"you wana get high? afterall it is 4/20."

"happy holidays, its 4/20"

4/20 

April 20th; A day where actual cannabis-smokers do the ganja. Also the day where a bunch of poseurs claim that they're gonna smoke weed on that day to try to be cool, but really don't.

So, I don't do marijuana on 4/20. Fuckin' sue me.

4/20 

Hitler's birthday and the anniversary of Columbine. A lot of people smoke weed on 4/20, which is cool but other than that it doesn't look good on the planets reputation.

I'm gonna go smoke weed now.

4/20 is a very awesome day, as long as you're not a parent who's kid got killed at Columbine.

4/20 

A holiday self established by marijuana smokers that takes place on April 20th.

Originally started by a group of college kids who would meet at a statue everyday at 4:20 PM to smoke weed.

Some other drug usage may take place but marijuana is the main one.

Pronounced "four twenty", if you say, "four hundred twenty" you'll look like an idiot.

Me: My dad got so baked yesterday.
You: Why?
Me: It was 4/20.

4/20 

The day to smoke weed. It is based off of what police say when they see people doing drugs ("We have a 4/20 on...").
It is celebrated internationally and people also wear green on that day. It is also Adolf Hitler's birthday, and the date f the Columbine School shootings. Pronounced "four twenty."

Yo man, I got some fresh Columbian weed for us to smoke tomorrow... after all, it is 4/20.
