Spliff
Ok, a spliff is, and always will be, a cannabis-tobacco cigarette. It is rolled using two papers (preferably zig zag 1-1/4, but if your a beginner, go for the king size). You take the two papers and overlap them in an 'L' Formation. You put your weed and tobacco (i recommend Midnight special or bali shag, because it's a wetter, loose tobacco) together in the papers and begin to roll from one end to the other. Technique is important, you want to end up with a cone shape because it burns evenly. Also, if you dont want flying bits of tobacco and weed to get in your mouth, just remember to add a crutch, or mouth piece (not a cotton filter), and your set!

can mean just a fattie, but a spliff is also a small, rolled up peice of cardboard put in the hitting end of a joint to act as a scoobie snack catcher. Also opens it up and lets it hit huge, like its supposed to.
