A chemical element theorized to be produced by the human body in a certain percentage of the population. The element is suspected to have a clear irreversible degenerative effect on the intellect. It is also a suspected contributor to the 'Bozone Layer' effect (please see Bozone Layer and bozone)
This element is not listed in the Periodic Table. It is illusive and has not yet been synthesized in the lab, and scientists suspect that they will never be able to. Naturally, there will never be a cure that reverses absurdium's effects.
Your idea has the trademark of absurdium.
This is the most banal thing I've heard. You must be on absurdium or something.
Did someone accidentally add few absurdium drops to your kool-aid this morning?
Man, I can smell the absurdium in your breath. It should be illegal for you to think.
