Data collected by editors at Oxford Dictionaries revealed a huge increase in usage of the word in 2017 compared to 2016. The U.K. election called for by Prime Minister Theresa May in early June is believed to have caused a spike in usage. The U.K. saw a huge turnout of young voters hoping to make an impact as they rallied behind Labour leader Jeremy Corbyn. Their collective actions were dubbed by the Guardian and other publications as a "Youthquake."
