The study found that women use the f-word 546 times per million words, while men use it 540 times per million words, which is a fall from 1,000 times per million words in the early 1990s. At that period, women were using the f-word 167 times per million words.
"It looks like there were a set of men who said [the f-word] a lot in the 90s, and they influenced the women to do it, and then it leveled," Tony McEnery, a professor at Economic and Social Research Council, told Refinery29. "As equality drives on, the idea that there is male and female language, that there are things which men and women should or should not say, is going to be eroded. Gentlemanly behavior and ladylike language is becoming something of the past."
