the.com/barbarism

means A crude or uncivilized act or expression — or, more pointedly, a word or usage that offends the self-appointed guardians of 'proper' language.

from From Greek 'barbaros,' meaning someone who babbled gibberish instead of speaking Greek — the sound 'bar-bar-bar' mocking the speech of outsiders. Latin borrowed it as 'barbarus,' and the Greeks and Romans applied it to anyone outside their own civilization, which conveniently included most of the people whose land they wanted.
