Shoreditch twat 

Usually a new media, fashion student, photographer-type person with a privileged digital or old school arts background who lives/works/socialises in London's East End area of Shoreditch. A Shoreditch twat has at some point also worked/lived/socialised in the near-by Brick Lane. A Shoreditch twat is defined by their Hoxton Finn haircut, 80s retro 90s fusion clothes (usually a suit jacket, blue ripped jeans, and white trainers/shoes), an ability to talk about pseudo-intellectual artistic bullshit with no relevance to the real world, completely up their own backsides, and a failure to comprehend that they are the laughing stock of the rest of the normal local (ethnic) population. The Shoreditch Twat has now been immortalised by the fictional Nathan Barley and serialised on TV by Channel 4.
