Comment Apples own dictionary app returns offensive words (Score 1) 200
From TFA:
The issue that the App Store reviewers did find with the Ninjawords application is that it provided access to other more vulgar terms than those found in traditional and common dictionaries, words that many reasonable people might find upsetting or objectionable. A quick search on Wiktionary.org easily turns up a number of offensive "urban slang" terms that you won't find in popular dictionaries such as one that you referenced, the New Oxford American Dictionary included in Mac OS X.
I'm sorry, but Apples own dictionary app that will return the definition of the words "cunt" and "nigger", and I don't think there is anything more offensive.
