Contrary to popular belief, this did not start off as a racist pejorative, but was an acronym dating from the
British Raj in India used to Identify Indians working for the Government. The acronym stood for Working On Government Service and those who were employed in that role wore an armbands with the acronym WOGS written on it.
Now, however, the original meaning has now largely been forgotten and the four commonest uses of the word "wogs" are as follows:
1. A pejorative noun for people who are non-white or of mixed race;
2. A noun used by certain
xenophobic British people to describe anyone who is not British
e.g. "Wogs begin at Calais.";
3. A noun used by narrow-minded, londoncemtric fuckwits to describe anyone who does not live in London;
4. A verb meaning to steal, "He wogs sandwiches off his mates." means he steals sandwiches from his friends, and unpleasant racist inference that all non-white people are thieves;
