Now, don't get me wrong, many people still throw around "slut" and "bitch" and mean it in a derisive, hurtful, negative way, but it does seem that pop-culture and the new generation have chosen to also use these words in a joking and less serious way.
In a recent visit to a bookstore I was amazed to see so many newly featured books with the F-word in the title of the book. I counted no less than three such books out of about 50 or 60 that were shelved together. What is going on that words are becoming meaningless or turning from undesirable terms to instead connote a seemingly preferable name. Someone from 1960 would hear bitch, slut or the F-word and run the other way. Now we seem to open our arms to such words.
Pop culture is largely to blame for this change of how we process such words. Popular television shows and movies have eroded the harshness that used to be associated with some terms. Shows like Girls and Sex and the City made it commonplace for friends to refer to each other as sluts or bitches. Musical lyrics also desensitize us to such labels when these words are used repeatedly and at times fondly. Social media is littered with the use of these terms.
It is an upside down world, where the bookworm or nerd is cool, a woman can proudly declare herself a bitch, and a slut can be seen as someone who is desirable and sexually empowered.
