When being called McCracken, you are refereed as a sexy mother fucker. You may be 1337 in all aspects of WOW and must worship him if you ever cross paths with him. He is the new Lich King, Do not be fooled by the ending cinematic, for Icecrown Citadel was merely a setback. McCracken is its own specie. It is a cross breed between a Nightelf and a Human commonly known as the Nightman.
"Oh my f'ing god it's McCracken! Here take all my virgin daughters because you are so awesome and you will kill me if I do not do your bidding"
