I avoid F-bombs when I can, using them only in key places for power, character arc or emphasizing a point.
Using the F-bomb shock when it is important to shock.
e.g. In the haunted movie, (the story-line is about a low-budget, indie-filmmaker and the movie he is making -- from his own pocket) there is a scene where the beautiful, lead actress who is trying to manipulate the filmmaker for control of the production, tries to seduce, fails and attacks with the line, "if you don't f#*k me, I'll f#*k you... trust me", as she follows him down the stairs from a bedroom, nude (different versions) with finger nails extended. It is a part of her character arc.
It is also a set-up that works, pushing the story forward with a sucker punch that no one sees coming...
I go for the 'real' (work hard at it, anyway)... trying to push the envelope with language and pace. I am still learning and certainly no authority or expert, especially with curse words...
Just because others use them every other word... I would never try to copy someone else's style in writing, directing, acting, etc. OR use curse words just because they are curse words...
My 2 cents. I am not rich or famous, just someone that has fun being creative.
