It is not uncommon for a set of identical twins to be esoterically parisologic.

Speaking of ambiguous words, I fear if you were to use parisology in a letter to the editor, unless you were very careful about the context, you would have people thinking it was something to do with Paris Hilton. And even with much care given to the context, you would still have many thinking of Ms. Hilton.

Dic.com wonders whether the word is from Greek. I wonder if it refers to the diplomacy of the French court.
