The state of mind that surpasses ordinary seriousness and is used only in the most horrible of situations such as the attack of manbearpig or the summoning of the mighty power of excelsior.
Al Gore's cerealness about manbearpig is so large that he has the need to say "excelsior" very loudly in public places.
Al Gore is a very cereal person.
People are not taking Al Gore cerial, even though his cerialness is super duper excelsiory.
