Gave you an ounce of shake? Why didn't he smoke it himself?

Are you sure you're not confused? Trim and shake are two completely different things. Shake is good weed that falls to the bottom of the bag/box/jar. Typically it's even better than the bud, because all the kief falls into it too. Trim is the junk parts of the plant that get tossed out by growers when they harvest. You don't have a bag of leaves, do you?

Shake should look like delicious stuff that goes into a joint.
