someone who is just naturally good at killing, fighting, inflicting harm. not with any weapons except maybe a knife or close range blade/ club weapon. using firearms does NOT make you a natural born killer.

also, Carlos Condit's nickname.

A no-honour Runescape clan. So NH that they kill RAW referres when it looks like they will lose. All their stats are gained through AFKing or macroing.

Frequently boast about their high pulls, but these usually consist of level 80s. Their only truly popular regular events are to RC pkill on PVP worlds.
I was trying to RC on world 65 but I got jumped by a load of nerds from Natural Born Killers. They got my glory, but then they have to share it between 10-20 lonely nerds.

Its a wonder NBK need warlords like The Buzz Hed when all they do is RC pkill.
