vibe check

A "vibe check" is a spontaneous assessment of someone's mood, the atmosphere of a room, or the general energy of a situation. Think of it as a mental radar sweep to see if the "vibrations" are positive, negative, or simply aligned with your own. It is highly informal and most commonly used among friends or in digital spaces to gauge if someone is doing okay or if a social gathering is going well. You might "pass" a vibe check if your energy is welcoming and relaxed, or "fail" it if you are being disruptive or bringing down the mood.
