hi sanso,
packing is when a person does a full inhale and then forces or pumps more air into their lungs using their toungue as a kind of piston. some people swear by this technique others think its counter productive as it hinders the relaxation state and if you are into greater depths may give a higher risk of dcs as you are carrying more nitrogen down with you but this occurs at big depths.
