CUTwC, as befits a club with an eminent history and its Oxbridge setting, sets great store by tradition. Typically, a tradition is something that has happened (or been said) at least once. The collective history of the Club means that newcomers may be bemused by frequent references to something that a member who left a decade ago may once have said. This section is intended to provide some enlightenment when it comes to the vocabulary of CUTwC.
