The Face with Steam from Nose shows closed eyes, a tense mouth, and puffs of air coming from both nostrils. It was designed to suggest triumph, but most people read it as frustration, anger, determination, or indignant huffing.
People use it after an annoyance, during a rant, or when acting fired up before a challenge. It can be serious, but it is often theatrically grumpy, like a cartoon character preparing to prove a point. Paired with strength symbols, it tends to mean determination rather than anger.
