How it's used
Originally referring to religious precepts, the term has expanded to cover any personal commitment or self-imposed restriction. It is frequently used in contexts involving diet, exercise, or breaking bad habits. Using it adds a slightly dramatic or humorous flair to the situation, framing the act of giving in to temptation as a significant moral or personal failure.
Examples
He said he was going on a diet, but he ended up breaking his vow and eating a late-night snack tonight.
