The rules are simple. Forumers with a death wish - or simply those who have incurred another's displeasure - will take to the field of honour. Weapons, methods*, seconds and limits must be specified in an initial post here. The duel will end when I determine the victor or one party surrenders. The only people allowed to post in this thread while a duel is on are the ones directly involved in the duel: the two duelists, the two seconds, the insulted party, I, and possibly a surgeon or funeral director.
Weapons
Historical weapons included rapiers, dueling foils and daggers, and pistols. People sometimes dueled with billiard balls and, in one case, with hot air balloons. For our purposes, the challenged duelist may decide whether the duel shall be fought with rhyming insults, non-rhyming insults, or some other form of linguistic weaponry.
*Some may find that they wish to have special methods or additions, such as the use of insults in accompaniment with rapiers.
