In Internet slang, a troll is a person who sows discord on the Internet by starting arguments or upsetting people, by posting inflammatory, extraneous, or off-topic messages in an online community (such as a newsgroup, forum, chat room, or blog) with the deliberate intent of provoking readers into an emotional response or of otherwise disrupting normal on-topic discussion.

If, therefore, someone shall say that the Roman Pontiff has the office merely of inspection and direction, and not the full and supreme power of jurisdiction over the universal Church, not only in matters that belong to Faith and Morals, but also in those that relate to the discipline and government of the Church spread through the world; or assert that he possesses merely the principal part and not all of the fullness of this supreme power; or that this power which he enjoys is not ordinary and immediate, both over each and all the churches and over each and all the Pastors and the faithful: let him be anathema.

(Pius IX, Constitution Pastor Aeternus or De Ecclesia Christi
