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)
