A "Happy Hookah" is a hookah pack that not only consists of shisha tobacco but also marijuana. There is a delicate ratio of tobacco to marijuana that should be observed. If the hookah is packed with too much marijuana it will burn, thus being wasted. A Happy Hookah can be a lot of fun especially when you are trying to kill two birds with one stone. It is common courtesy to inform fellow hookah smokers that the hookah has been packed happy. However it can also be very funny if you do not
-Hey dude wanna smoke some hookah?
-Sure man, but I also was hoping to smoke this marijuana
-Oh I know! Lets mix that shit together
-Nice thinkin dude, now we got ourselves a happy hookah
