A new media person with a 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 rubbish 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 population. The Shoreditch Twat has now been immortalised by the fictional Nathan Barley and serialised on TV by Channel 4.
Look at that Shoreditch twat walking down the road.
