How many times in one sentence can you drop the F-bomb?

While at the local coffee house, I could not help but overhear a woman seated not far off. I was passing away a few moments until a meeting I had to attend and was not trying to ”ear hustle” her conversation but she was talking SO LOUD, it was hard to ignore her. It seemed as if every 4–6 words out of her mouth were dropping an F-bomb. How much do you use it, and how much in one sentence? Do you believe it makes your speech or conversation more pertinent, colorful, or powerful?
