Cashed Bowl

If you don't get a good hit, or you know the next hit won't be good, don't pass the bowl. Ash hits are dirty and they won't get you high. Instead, hand the pipe or bong back to the person who's loading the weed. When you're not quite sure if the bowl is totally cashed, blow lightly across the top of the bowl. This will send the ash flying, but will leave the bud intact. (Don't attempt this while indoors.)
