Petulant may have changed its meaning over the years, but it has retained its status as “word most people would not use to describe themselves in a job interview.” Hailing from Middle French and Latin, petulant began its English tenure in the late 16th century with the meaning recorded in our unabridged dictionary as “wanton or immodest in speech or behavior”—in other words, “lewd” or “obscene.” The word eventually softened, at least somewhat, from describing those who are forward in—shall we say—[prurient](https://www.merriam-webster.com/dictionary/prurient) ways, to those who are forward by being merely rude and angrily bold. Today the word is most commonly used to describe someone acting snippy and snippety, snappish and snappy, displaying an often childish ill or short temper of the kind that tends to arise from annoyance at not getting one’s way.
