A disease that causes extreme flairs of herp derpness. It's not a deadly disease but it is highly contagious as it is airborne so if you find your self suffering from Herpatitus-D, contact anyone you have been around so they can be checked out immediately. There is no cure for Herpatitus-D and it is hereditary so watch who you hang out with as they could be carriers and not know it themselves. There are treatments for the flair ups with a soothing ointment which can be applied five times a day. The best way to deal with HD is to be taken out back behind a shed and be taken out old yeller style
An example of Herpatitus-D is claiming yourself King Herp of all the Derpdom.
