A derogatory sound used to emasculate any blatant attempts to show off through anecdotes or other verbal communication. However, most people who do show off through long boring anecdotes fail to realise this mocking gesture, which allows the word to be used with impunity. For full effect it must be said in an exaggerated upper-class accent.
