It refers to the Kelvin scale of temperature. Thoretically, it cannot be reached.

Absolute zero is the theoretical temperature at which entropy would reach its minimum value. The laws of thermodynamics state that absolute zero cannot be reached, because this would require a thermodynamic system to be fully removed from the rest of the universe. A system at absolute zero would still possess quantum mechanical zero-point energy. While molecular motion would not cease entirely at absolute zero, the system would not have enough energy for transference to other systems. It is therefore correct to say that molecular kinetic energy is minimal at absolute zero.
By international agreement, absolute zero is defined as 0K on the Kelvin scale and as 273.16C on the Celsius scale. Absolute zero is also defined as 0R on the Rankine scale (similar to Kelvin but measured in Fahrenheit intervals) and 459.67 on the Fahrenheit scale. Although it is not possible to cool any substance to 0 K,[2] scientists have achieved temperatures very close to absolute zero, where matter exhibitsquan ...more

0 degree Kelvin is the absolute Zero in temperature Scale, as all gases ,if they remain in gaseous state will be of Zero Volume, which is impossible by general properties of matter at -273 degrees celcius.Hence the nameIn any number system if a=x ,then a-x =0, here 0 means identically opposite & prvides us with negative number concept. / Or a+x = a gives us the concept of Zero. It is Addition for Identity & bears the meaning absolute Zero. It matters a little whether the number system is open / or Closed one.

Absolute zero is the temperature o degrees in absolute or -273.16 degrees in Celsius, which has never been reached (will not be reached also) though very near to that has been reachable. At this temperature all molecular motions cease.

You have got elaborate and scientific answers to your Q...so will not further elaborate.
However...answering from a lay mans point of view...I would define an absolute zero in the case of personality or results...
It would mean that the person or the result has reached the nadir of negativity...
that there couldnt be anything positive from the outcome or person...
that spending valuable time with such a person would negate all positivity in acqaintances...
that I would prefer to stay away from a person who would give absolute zero vibes...:-))))))))))))
regards !
