That person is turning their nose up at me for no apparent reason; they must be one of those posh southern twats.

cambridge university has a particular slant on a posh twat. The graduates of cambridge tend to be in love with their own success and are secretly jealous of anyone even vaguely more successful than them. For example any other cambridge graduate. The most successful moment for these people was getting into the college, graduating and then spending the rest of their lives "I went to cambridge", getting married in cambridge and marrying other cambridge graduates and then desperately spending their lives clawing onto their pocket of success and having to fund their superiority and status anxiety.
cambridge posh twats "I can't go to my cambridge reunion because I haven't achieved anything and no, a husband, children, successful career and my own home do not count as any palpable success, please don't call me a cambridge posh twat you chav".
