Nerdfighter 

Nerdfighters fight for nerds not against them, similar to a freedom fighter. The goal of a Nerdfighter is to reduce the amount of suck in the world, otherwise known as worldsuck. Unlike regular humans, who are made of flesh and blood, Nerdfighters are made of awesome.

Nerdfighters will rule the world someday.

Nerdfighter Gang Sign 

Used by Nerdfighters, followers of John and Hank Green, AKA the Vlogbrothers. Done by crossing your arms in front of you, palms facing inward, and doing the Vulcan Salute with both hands.

If you see someone do the Nerdfighter Gang Sign, you know not to shoot.

Nerdfighteria 

Refers to the Nerdfighter community which has grown up around the Green brothers' Youtube channel, vlogbrothers.

Although the population of Nerdfighteria is scattered internationally, the citizens have united numerous times to decrease worldsuck through super secret projects, other charitable events, scavenger hunts, video montages, happy dancing, and gatherings.

"Hello, Nerdfighteria!"

Nerdfighters 

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.

Nerdfighters, we fight with our brains.
Nerdfighters, we bring the frakkin' pain.

"Dude, did you see that geek over there?"

"Man, that was no geek, that was a NERD FIGHTER!!!"

"What's the difference?"

"You don't wanna find out..."
