Absolute means complete, with nothing held back or limiting it. Absolute power, absolute nonsense, an absolute majority.
The exact uses matter: an absolute majority is more than half of everybody, not just more than anyone else, and absolute zero is the temperature below which nothing can go. As an intensifier it has worn thin — absolute rubbish means very. Note the Latin, meaning loosed from.
