Used to refer to a low grade type of marijuana. Usually old cannabis that has been flattened and squashed for smuggling purposes and is very old(5-15years). Usually lots of seeds and stems, an earth smell, brown coloring and a bad taste while smoking. Also know as Mexican.
I want to pick up some weed from my friend but he says he only has desert cryp. Arrgh. Looks like we are going to be coughing a lot...
