This article is part of an effort to understand the enthusiasm, attraction and admiration of the organization “Islamic State in Iraq and Syria” (ISIS) among the young Muslim female in Western Europe. The article specifically focuses on microblogging (Tumblr and Twitter) contents of young Muslim girls from Western Europe. The study offers a review of ISIS-adoring Tumblr fangirls in the West through the prism of cultural interpretation. The young girls, whether themselves manipulated or manipulating others, become part of a worldwide viral system produced in perfect unison and generating propaganda enticing more and more young Muslim girls in the West to become viral ISIS recruits. After maintaining for a while Tumblr and Twitter accounts, some of them even undergo the “giant leap” and migrate to the “Islamic State” in Syria, continuing there to reinforce their blogging and twittering efforts, reporting on their daily lives and attempting to tempt or to trap more young girls to join the new “Islamic State”.
