A nerd who fights (against the decepticons -- also known as popular people).
One who is, instead of being made of organs and tissues and whatnot, made of awesome.
The word originated in
John and Hank Green's video log projected, called vlogbrothers. While
John was in an airport one day (curse those
grey speckled walls), he saw a video game called Nerd Fighters.
Thus, the legacy of nerdfighting began.
