What it means
A vibe check is a quick, informal read of someone's mood or the energy of a room, deciding on the spot whether the vibes are good or distinctly off. Pass it and you are welcome, fail it and people quietly keep their distance.
Usage examples
"He walked in grumbling and instantly failed the vibe check."

Where it comes from
From vibe, short for vibration, the feeling someone gives off, plus check, a quick inspection. A vibe check is exactly that, a snap inspection of the atmosphere in the room.
