John Oliver used this strategy effectively in his HBO coverage of the 2015 Paris Bataclan attack by calling the attackers "Unconscionable, flaming assholes, possibly working with other fucking assholes". Donald Trump has recently begun calling terrorists "Losers". George W. Bush called Al Qaeda members "thugs and killers". You are also correct that Daesh is preferred in Arabic media over the term ISIS, and although the former is really an acronym, it is close to to the Arabic words 'Daes', 'one who crushes something underfoot' and 'Dahes', translated as 'one who sows discord'. Members of the group also really hate the term being used to describe them, which helped spur it's usage. It's a strategy that's been used for some time and has proven effective in some cases in discouraging copycat behaviors.
