Hufflepuffer 

Someone who smokes marijuana. The word is derived J.K. Rowling's Harry Potter series, where Hufflepuff is one of the four Hogwarts houses, known for producing students who are exceptional in the art of herbology. We all know what that means. *wink wink* It is also an excellent name for a bong.
