It is an unpleasant and derogatory term for a person born to unmarried parents. As a 'bastard' myself, and knowing many 'bastard' children I object to the word still being used fairly commonly. You wouldn't use the 'n' word or many other outdated derogatory terms, so why is it still acceptable to use this offensive term, including on MN to describe undesirable things 'bastard neighbours/drivers/insert word'?
Aibu?
