hit the open man

Hit the open man is a session wherein there is one less smoking device being used in the session than there are smokers in the session. It is called hit the open man because when you are done your toke, you pass your pipe/joint/bong to whoever it is in the session without a smoking device, resulting in efficient and quick stonage.

However, one must be careful when mixing pipes and joints. If a member of the session has mega cannonball lungs, and they notice you are waiting for someone to take a fat pyrex off your hands, they may toke their joint until the cough inducing pyrex has made its way to a new open man. For this reason, when mixing smoking devices, make sure you're not sessioning with weak lungs.
