grossly wicked and vile; as, a flagitious proposal. Flagrant marks
the vivid impression made upon the mind by something strikingly wrong
or erroneous; as, a flagrant misrepresentation; a flagrant violation
of duty. Atrocious represents the act as springing from a violent and
savage spirit. If Lord Chatham, instead of saying "the atrocious
crime of being a young man," had used either of the other two words,
