It’s an adjective that describes something that relates to Bohemia or style originating from Bohemia. This word is probably used most frequently among people involved in the fashion industry or used in magazines that revolve around telling people about the latest fashion styles. The term boho seems to be a clipping of the first three letters forming the word Bohemian, and then an “o” is added to the end to either give it more of an adjective quality or to have the same “o” sounds for the first and second syllables to have more sound similarity or rhyming effect in order to make it easier to say.
