I am happily reading a 'Brief History of Swearing' whose main title even wouldn't get past the mods on a bad day. I long to quote from it but can't really.
Zounds! 'Sblood! The bad words come and go. These days racist epithets are among the most offensive... and are nevertheless embraced sometimes by their ostensible targets and worn as a badge of pride, the Y word and N word among others.
I am hoping the author, a sprauncy American lady, will get round to the very bizarre Jamaican canon of menstruation oaths (one of which I have made my password to this site).
