A cannabis joint or spliff made from 3 standard-sized cigarette papers. Two papers are stuck end-to-end with an overlap and the gum strip on the same side, and the third is used to secure the non-gummed side of the first two papers. The purpose is to make a spliff or joint large enough to pass around.
Have you got a king size Rizla? No mate, I only have regular ones for my rolling tobacco, you'll have to make a threeskin.
