A freshly-packed bowl is full of green flower. The first hit from this bowl will be the most flavorful, and possibly the most potent. It's a generous act of friendship to offer someone "greens," the first hit from a freshly-packed bowl, and some consider it good manners to always offer guests greens. If you do receive greens, the polite thing to do is to "corner" the bowl, holding the lighter at the edge of the bowl so that only a portion of the green weed is lit. That way, whoever smokes next can also get greens.
