Billy and sesh

A term used to define the act of smoking cannabis. It comes from the words Billy which means bong and sesh which means to smoke weed out of a bong. However, this may be referred to as a euphemism in order to disguise the act. This can be done by referring to the phrase as the friends Billy and sesh.
