SNOB

sine nobilitate
«The word 'snobbery' came into use the first time in England during the 1820s. It was said to have derived from the habit of many Oxford and Cambridge colleges of writing sine nobilitate (without nobility) or 's.nob.' next to the names of ordinary students on examination lists in order to distinguish them from their aristocratic peers.^[1] These common, but typically wealthy students would then emulate symbols of aristocratic status (driver, maid etc.), and were then in turn mockingly identified as 'snobs' by the aristocrats. After the later changing of the meaning of the term 'snob', people with such emulation behaviour are now referred to as 'snob victims'.»
