Although, for social reasons, you don’t want to have your young children running around saying it (particularly in public), there really is nothing wrong with the word. It doesn’t demean or slander anyone. It isn’t racist, sexist or any other “ist”. It’s just a word that can add emphasis or can be used as a synonym for sexual intercourse. Yes, it can be used in conjunction with other words to be generally insulting, but otherwise offers no harm.
