For me finger hash is when ive been smoking a good bit and a lot of hash well keif i suppose is stuck on my thumb and first finger(sp? ..im hungover and the word looks weird). I usually just lick my finger or thumb and put the hash into a joint, I think im gonna start collecting keif now since I always have a shit load of it but it's usually packed and sent on its way...over the hashy hils and into the endo cloud...
