Halloween originates from All Hallow's Eve. Nowadays it's mostly a marketing platform for major stores but there are still some traditions that are fun.
If you're a kid you dress up in a costume and walk around your neighborhood collecting candy from your neighbors. You also carve pumpkins and put lights in them.
If you're an adult you dress up in a costume, go to a costume party, get wasted and try to bang the slutty chick in the Harley Quinn costume.
