The N word.

[donquixote99]

If someone thinks up odd personal meanings for words, such as 'nigger' means 'out-of-work,' it's likely to pose difficulties for communication. Moreover, since the word used as a racial slur is considered a sharp and shameful-to-use insult, one may suspect the one proposing such a redefinition is seeking to duck condemnation, thus allowing use of the word in a double sense. That is, to fellow bigots it signals one thing, while that meaning becomes deniable to critics. This is an example of passive aggression--transgressing behind a pretense of innocence.
