a pejorative for members of what is variously called "the Islamic State of Iraq and
Syria" (
ISIS), "the Islamic State of Iraq and the Levant" (ISIL), or "the Islamic State" (IS). It is based on "Daesh" or D-A-ʿI-SH, its acronym in Arabic (for al-dawla al-islamiya fi al-ʿIraq wa-al-
Sham) + "bag", playing on the similar sounds of "daesh" and "douche".
