The name comes from Vietnam. The vietcong used to call the helicopters "saghasjlgj" which translates to "MutteringDeath" ; because American helicopters used to pwn nub villages and Ho Chi Ming lovers........and it sounds like somebody muttering while their flying.
Hater of the news guy with initials HR.
"MutteringDeath destroyed my pissant village and killed my family, but then he left and now i'm gay for Ho Chi Ming."
HR: "I'm here in Vietnam today to talk to some squinting eyes about the battles in Vietnam's war with America, hello my fine lad, you look like you finger your hole, do you have any stories about the war with the evil empire?"
Viet Cong: "I was just minding my own business mining ore for Nod, when MutteringDeath shows up to destroy my base"
HR: "Wow sounds like fun"
VC: "No it wasnt fun you cunt, all i hear is this whub wob whub wob whub wob, and then there were bullets, bombs, and fire all over"
HR: "Is that the noise now?"
VC: "What are you talkin.....Oh shit he's back"
HR: "Aw lame, he just shot my arms and legs off"
