A Church of England state secondary school in Acton, West London that likes to pretend it's private when really it's just full of wet dons (and that's just the teachers). If you want decent GCSE grades and least 1 mental illness this is the school for you. Don't get too comfortable- if you're dumb they don't mind kicking you out for sixth form so they can take private school students instead. To identify a Twyford student just look for an ankle length skirt, a school logo branded bag (because it's illegal to have anything else) and a teenager who looks one assessed homework away from a mental breakdown. Mostly full of middle class teenagers who are either nittys, neeks or chavs.

Briefly, "the realization that each random passerby is living a life as vivid and complex as your own." Originally from the Dictionary of Obscure Sorrows, which has a lot more beautiful neologism definitions like this you might enjoy.
