The early 18th century in London was a very good time to be a douchebag, especially if you were an aristocrat, and especially if you were one whose sole desire in life was to wreck all the shit you had ready access to. In 1710, gangs of aristocrats were rife. They were heavily themed on specific types of mischief, and had names straight out of The Warriors. There were The Blasters, who flashed women; The Sweaters, who surrounded random guys from every direction then stabbed them in the ass with their swords for "turning their back on a gentleman"; and The She-Romps Club, who kidnapped girls into their clubhouse and made them walk on their hands so their skirts would fall over their heads.
Meanwhile, you can't even look at someone doing yoga without throwing out your back.
Still, it wasn't all fun and stabbing: The most feared of these groups was a gang of young men called The Mohocks (or Mohawks, after the Native American tribe). They gained their notoriety because of their willingness to assault men and women alike with their special move of choice: a gruesome attack they referred to as "tipping the lion," wherein a passerby's nose was smashed in and then their eyes gouged out. There were reports of victims with their hands and ears sliced off and of old women stuffed in barrels and rolled down a hill. Some say The Mohocks carried a specially constructed iron instrument to rip open the victims' mouths. Other sources (such as Hunter S. Thompson, a man who knew his debauchery) insist there was a second mutilation gang called The Man-Killers and the two clubs were caught in a game of keeping up with the Joneses (murder sprees).
