But that expression of "violently in love" is so hackneyed, so doubtful, so indefinite, that it gives me very little idea. It is as often applied to feelings which arise from a half-hour’s acquaintance, as to a real, strong attachment. Pray, how violent was Mr. Bingley’s love?

– Jane Austen

Pride and Prejudice, Chapter 25. Mrs. Gardiner questions Elizabeth’s claim that Mr. Bingley was “violently in love” with Jane.
