EOM is misspelling his posts on purpose to try to disguise the fact he is an American (Gadahn). And his use of Amerikkka and his posting of the lyrics of Horror Movie as his pre-9/11 taunt on the MSNBC board illustrate his Heavy Metal roots he supposedly gave up when he became a Muslim. EOM=Gadahn. Bet on it.
With that in mind can you think of anything in that genre that would explain his handle. EOM
