FLYTING WAS MEDIEVAL ENGLAND'S VERSION OF AN INSULT-TRADING RAP BATTLE, by Tao Tao Holmes (Atlas Obscura)
Imagine a world that had swapped its guns for puns and its IEDs for repartees. Such a planet is possible if only those in power would manage their conflicts with flyting, the time-honored sport of verbal jousting.
Flyting is a stylized battle of insults and wits that was practiced most actively between the fifth and 16th centuries in England and Scotland. Participants employed the timeless tools of provocation and perversion as well as satire, rhetoric, and early bathroom humor to publicly trounce opponents. The term “flyting” comes from Old English and Old Norse words for “quarrel” and “provocation.” 'Tis a form of highly poetic abuse, or highly abusive poetry—a very early precursor to MTV’s Yo Mama and Eminem’s 8 Mile.
