The item of marijuana paraphernalia that is evolved when one is so

gravity bong into the bath with oneself.
Usually in the form of a 2-liter soda bottle with the bottom cut off, the bathtub bong is always the
piece in a marijuana smoker's collection that he has had the most fond memories with.
Because you can't call yourself a
pothead if you haven't passed out in a bath full of warm
bong water.
