The phrasal verb "flip out" is predominantly used in informal speech to describe a sudden and extreme reaction, usually of anger, surprise, or shock. Common in conversational English, it is often used to characterize someone's emotional response when they lose composure or become overly excited or agitated. For example, "She flipped out when she saw the mess her dog made." In more formal contexts, other terms such as "overreact" or "lose one's temper" might be preferred. "Flip out" carries a slightly humorous undertone, and it can sometimes indicate more of a dramatic overreaction, depending on the context. This informal expression is typical in everyday spoken language, particularly among younger people, and is frequently encountered in media like TV shows and movies that aim to convey relatable, realistic dialogue.
