A hit of pot smoke taken from a gravity bong. These are generally high-volume inhalations (2 litres to 1 gallon, usually) and yeild large quantities of smoke, usually resulting in excessive coughing.

One gravity hit of medium potency pot is usually enough to get fairly stoned.
I must have smoked a half gram in that one gravity hit. It blew my head off, now I'm pretty baked.
