The 20th day in the month of April. Also known as St. Jackass Day. Followers of St. Jackass celebrate by making "lol 420 blaze it" jokes. Celebrated by sheeple.

a word used to express the time or date in which you will meet up and smoke a whole fucking shitload of marijuana with all of your friends.
Also a holiday held on April 20 where everyone in the worlds celebrates the fact that they are raging potheads.

This supposed holiday was actually created by a Governmental Agency in an attempt to secure, arrest and imprison marijuana users. In 1957 a secret Government society ironically named "Numbers" was to spread word of a holidy. One that celebrated when marijuana was first discovered. Beware of this holiday, for it is more likely a Government conspiracy to attack marijuana users. Nah, I'm just fucking around. Does sound like something a pothead would say though huh? Paranoid anyone?
