Swearing

The swear words used in the English language are atrocious. Most these days (post-racism, post-misogyny, post-xenophobia) are related to sex, possibly deriving from victorian prudishness, and have unfortunate consequence of perpetuating the stigma of sex in society. And yet the worst thing a person can be is arrogant. There is just one noun, egotist, to call someone that's arrogant. And even that hardly rolls off the tongue.
