HI/AF in a heavy metal band logo, green lightning bolt and all, on a women's crop top for people who are high as f*ck and proud of it. It's the stoner version of rock and roll swagger. The whole 4/20 thing started in 1971 with a group of California high school kids who met at 4:20 every afternoon to smoke, and it grew into a worldwide holiday. Wear it to the dispensary or straight to the couch. Good gift for the weed lover who always has a lighter.
