My pick is Five Finger Death Punch and the obvious answer is Ivan Moody. The guy radiates that alpha-male wannabe energy and it definitely rings through all of the songs he has written and performed with this band. The guy is just a prick and a self-victimizing asshole.
I think he’s the primary reason FFDP is mocked so badly.
Least metal thing of all time. I don’t know if he apologized or what because everyone seems to have forgiven/forgotten.
I think he’s Unforgiven
Sad but True
