Banduo

Banduo: noun. A musical term used to describe a band, which is composed solely of two members. Examples of this include The Black Keys and The White Stripes. However originally the word was used to explain the machine used to give rubber bands their stretchiness and bendiness. It is unknown why the meaning of the word changed so radically, but it did so around 1822. The word has also been used in some parts of Vatican City as an alternate spelling of the banjo. The Papal Office has on many occasions refused to give any explanation as to why this is and it shall probably forever remain one of life's mysteries.
