Ostracism - an English word of Greek origin...
In Athens, the original democracy, they used to vote for the person they hated the most and write their name on a piece of pottery (ostraca in Greek). The "winner" was exiled for a decade or so. Hence, the English word 'ostracism'. Usually the most popular and famous was also the most hated and voted for.
