What—and Whom—Gets Described as impetuous
Impetuous is often applied to various kinds of behavior, and to the people who exhibit that behavior. Impetuous behavior is often impulsive behavior: the impetuous among us act without thinking long and hard about the consequences of their actions. They are rash and reckless:
The new monarch—the first grandchild of Queen Victoria and Prince Albert—was boastful, arrogant and impetuous. He spent most of his waking hours talking, arguing, shouting, predicting, threatening and generally unbosoming himself of his latest preoccupations to whomever happened to be within earshot. Even when he made the utmost effort to restrain himself, the indiscretions kept slipping out.
— Christopher Clark and Andrew Preston, The New Statesman, 1 Nov. 2016

Passion, ever an inspiration for impetuous behavior, is also often implied, as those guided by the heart take ill-considered action:

Did You Know?
When we borrowed impetuous in the late 14th century, we used it of people and their actions. About a hundred years later, we added another sense to describe physical things like wind or storms or seas. (We don't use this second sense much anymore.) The word comes via Middle French from Late Latin impetuosus, which is from impetus. Latin impetus (which of course gave us our own impetus, meaning "driving force") essentially means "assault," but it also has figurative senses ranging from "violence" to "ardor." Our impetuous has a similar range of meaning, from "violent" to "passionate." It also carries the suggestion of impulsiveness. Often, we put a light touch on the word, as when we refer (somewhat longingly, perhaps) to our "impetuous youth."
