A toilet, loo, lavatory or WC is a plumbing fixture and disposal system primarily intended for the disposal of the bodily wastes: urine and fecal matter. The word "toilet" can be used to refer to the fixture itself or to the room containing the fixture, especially in British English. In North American English the word "toilet" refers solely to the fixture itself and not to the room that contains it, thus asking for the "toilet" would seem indecent. Instead, the euphemisms bathroom, restroom, washroom, men's room or ladies' room are preferred.The flush toilet was originally invented in the Indus Valley Civilization.[citation needed] The modern flush toilet was developed by Sir John Harington, but due to slurs published by himself and being ridiculed in England for his invention, his toilet was never mass-produced
