look up any word, like blumpkin:

A cigarette consisting solely of the wicked weed. This, to my understanding, distinguishes it from a 'joint,' which is traditionally rolled with a combination of tobacco and marijuana. However, the american tradition of smot-poking consist mostly of rolling marijuana-only cigarettes, therefore the words 'reefer' and 'joint' are interchangeable.

The word 'reefer' probably comes from sailing terminoligy: when you 'reefer' the sails you narrow them and roll them up, and considering that modern marijuana use originated in the lower class, it's easy to see how a poor deckhand would associate this with the way he rolled his marijuana cigarette.

God's most glorious gift to mankind: green, weed, bud, dope, pot, herb, grass, the great smoke-shit. This wonderful plant, when rolled into a joint, blunt or packed into a bowl etc., is the single most effective way to relax and be at ease known to man. It can be smoked from joints, blunts, pipes, bongs, hookahs, one-hitters, bubblers and indeed just about anytihng.

Slang term for marijauna that come from the early 1900's movie reefer madness where a man smokes bud and it makes him go insane killing his whole family. Alot of people belive that this movie played a key role in making marijuana illegal by scaring the public.
