420 is alot of things good and bad, example it is planting day for out doors, it is hitlers birthday, it is a part in the bible which says some stuff about these things are here to use, I have herd in some places it was a cop call for marijuan some way or another. Its is stoner code for light it if you got it basical and it has become a hoiday to celebrate twice a day or if you like me its always 420 somewhere, like right now in my bathroom its always 420 hahaha
