Chop (or spin) is a mixture of tobacco and weed, smoked through a pipe or bong.
Known for its horrible taste and rediculous rush. It's also damn addictive. Hence why only a few smoke chop, but the ones who do tend to smoke it exclusively.
Term used mostly around New Zealand, possibly other parts of the world.
Chop? It's rediculous. Smoke a cone in one, it feels like shooting weed into your veins (if that were possible).
But you then notice yourself wanting one two minutes later.. then another.. then another.
