So stop staying that! Almost noone refers to female dogs as "Bitc#es". The dictionary does not control meaning.. context and usage does. And in 2013, the word "B" does not mean "female dog". Language is alive and cannot be contained in any book. Everything on the page is a snapshot of a moment in time. Language constantly changes.. and it actually takes a gargantuan effort to hold it in place for any period of time. The word Bitc# just means "a mean or lowdown woman." It's meaning is completely associated with a certain kind of behavior.. and when used in the relative way that black people often use language, it expresses a diminished opinion of ones character. When used in reference to men, it represents a doubly diminished opinion of character through the association with so-called "unmanly" behavior. There is quite a bit of subverted language in African American circles.. "Bad" meaning "Good" is one of the clearest examples. And what I've seen.. very generally speaking.. is.. the further the people feel from the mainstream society, the more likely they are to use subverted language. Said another way: when you're living upside down, right-side-language don't make much sense. And so.. "dam#.. I love this sh##.." and.. "that bitc# was bad.." become positive relative expressions. Of course.. the words alone do not contain the full meaning; the final determination really depends on Tone.. Physicality.. and finally.. Context.
