Zig-Zag's - papers used for rolling cigarettes. White is the thinnest, and is distinguished by it's watermark of the zig-zag man and are preferable for rolling joints, but one must be careful not to roll wet pot with one's white zig-zags or one will have trouble getting one's joint to burn properly, the blue papers are a little heavier and are better for rolling cigarettes, or pot which was either freshly picked or "moisened" by your local pot supplier. The green zig-zags are the thickest, and wet proof, therefore they are most valuable for water-skiing, cliff jumping, and deep sea diving. Wherever you live, they'll likely cost you less than the price of a chocolate bar, so even if you don't smoke cigarettes, or pot, I really suggest picking up a pack, simply because they're cool.
"Hi, could I get 6 packs of white zig-zags please."
"Do you think you can really use the green zig-zags under water?"
"Zig-zags are like the world man, it's like you got the papers, keeping everything in, like the ozone and stuff, and like, the pot is like all the trees and people and stuff, and like, they're all like living and stuff.... and then you like, burn it, and like it gets you totally stoned and stuff."
