The new, accepted substitution for the word "Please". But, only when used in the plural sense. In the singular sense, it just means what it is. Also, if you are into being more cultural, you may use it in Spanish as "putas" instead of "por favor", or any other language of choice, as long as the plural sense is used. Also to use "bitch, bitches" to say "bitch, please" is not an acceptable use of "bitches". Bitches, remember that it is good practice to be polite.
"Can you please hand me the remote?" would then be "Can you bitches hand me the remote?"
