hump day 

started out in Vienna, VA as a huka-chilled day after school consisting of 3-15 of your closest friends. It later progressed (or digressed, as some may say) into a day in which you toked up before, during, and after school..then later passed out after your family appeased your munchies with dinner. One must wear greend on hump day in roder to officially celebrate. This year 4-20 just happens to fall on a hump day. Happy humpin humpers..

huka hump day can be celebrated not only with the preferred reefer. Healthy substitutes such as alcohol may suffice
