4/21

When you forget to get weed for the actual 4/20, and can't find any because everyone is using theirs, or you are otherwise unable to celebrate on the actual day. So you therefore celebrate the day after...4/21

Sarah: Hey, do you have any weed?

Megan: No, and I can't find any from anyone else!

Sarah: Damn... 4/21?
