Jargon : special words or expressions that are used by a particular profession or group and are difficult for others to understand.
Idioms have a way of uniting people through a shared understanding of a phrase whose literal translation often makes little sense. Learning a language is difficult enough and slang adds another layer of confusion. I witnessed this confusion while working with a friend from another country; whenever an idiom was used in conversation I could see the bewilderment on their face. In these works I created a literal translation of idioms to bring to light the ridiculous way language twists words while also magnifying the confusion this slang term could create when communicating cross culturally. As language unites groups of people through a common thread it also separates us from others.
