Americans are learning a whole new type of names, or noms de guerre. While the earlier PLO and Fatah celebrities like Arafat (Abu Ammar) and his pals made the “Abu” a familiar term to some Westerner media types, they were few and far between. That is because the honorific Abu is socially mostly common in the Arabian Peninsula and the Gulf, as well as Iraq and parts of Jordan and Syria. In our region (that I mentioned), almost everybody who is adult male is Abu somebody or something, even if he is not really Abu anybody or anything biologically.
ISIS leaders and fighters apparently have adopted this naming system, an imitation of the very early Muslims from the Hijaz part of the Peninsula many of whom often went by such names. Here are some real and suggested such noms de guerre for the IS denizens, announced and unannounced:

Abu Bakr Al-Baghdadi
Abu Khalid Al Canadi
Abu Bieber Al Canadi
Abu London Al Crazy
Abu Qutada Al Polygami
Abu Goatee Al Horni
Abu Al ‘Alaa Al Mo’arri
Abdul Salam Al Nabulsi
Abu Brood Al Saudi
Abu Al-Saud Al Abiari
Abu Jumbaz Al Aflangi
Abu Sisi Al Masri
Abu Assad Al Souri
Abu Zayed Al Dhabiani
Abu Muslim Al Khorasani Al Wahhabi
Abu Thani Al Qatari
Abu Turkey Al Saudi
Abu Prince Al Harami
Abu Izzat Al Douri

Americans celebrities who might consider adopting some Jihadi noms de guerre and the most likely acquisition:

Abu Bama Al Hawaii
Abu Bo Al Amriki
Abu Biden Al Delawari
Abu Nancy Al Pelosi
Abu Kerry Al Bostoni
Abu Hegel Al Nebraski
Abu Clinton Al Chapaqui
Abu Petraeus Al Spooki
Abu Mitch Al Kentucki
Abu Badhair Al Trumpi
Abu Sarah Al Alaski Al Wasilli
Abu Kim Al Kardashi
