The Americans coined 'boob' and left it to the British, I think, then now prefer 'tits', I think
Can you tell me which one is more acceptable in polite context or if they are equivalent, what is their connotation? Do you consider them vulgar? When I was in England boob seem to be an acceptable word
The usage to associate tits with boobs however, is purely sexist. In polite society you should mention neither, referring instead to the bosom that @Robusto mentions, or breast, but only when you must. "
