Some of the most irritatingly pretentious and retarded individuals you will ever meet. They watch endless hours of unfunny v-logs, leave the stupidest comments on youtube, and buy t-shirts with logos of video game characters they don't even recognize. They claim to fight 'world suck', but in reality they're just painfully average and moronic losers who have regressed to the age of twelve and send all their money to balding, fat and childish adult losers who find self-worth in pretending to be cool.

People who instead of being made up of cells and organs and stuff are actually made out of awesome.
They fight decepticons on behalf of Nerds everywhere!

Nerds who fight, usually against popular people. This term originated from the videoblog Brotherhood 2.0. John Green, one of the two participants in the videoblog, noticed a game called Nerd Fighters at an airport. Eventually, the viewers of the videoblog began being dubbed nerdfighters.

Nerdfighters are considered to be "made of awesome" by John, Hank (the other participant in the videoblog), and other nerdfighters. The nerdfighters often send in pictures of nerdfighter related activities to the videoblog, such as nerdfighter embroidered pillows. It is unknown what will happen to nerdfighting when the videoblog ends.

A nerdfighter is a person who is proud to be nerdy and intelligent, and who fights to decrease WorldSuck. Nerdfighters are not composed of cells and tissue, but instead made entirely of awesome. Nerdfighters are known to perform their Happy dances when they are joyful, and each Happy dance is unique to its respective Nerdfighter. Nerdfighters are diverse in their hobbies, which can range from writing Nerdfighter songs to playing D&D. Nerdfighters have also been described as someone who is "Outgoing, intelligent and awesome enough to accept nerd as a compliment". The polar opposite of a Nerdfighter is a Decepticon.

Made of awesome people who are nerds. Nerdfighters call themselves nerd with a compliment, and their are many categories.

a nerd that fights for the pride of nerds everywhere, usually against the popular people. Coined by brothers John and Hank Green in their videoblog Brotherhood 2.0. Based on a videogame John saw in an airport.

Nerdfighters are proud to be Nerds and fight to decrease WorldSuck.

Instead of being made of bones and organs, they are physically made of awesome.

Can be easily identified by the use of the word jokes.

The opposite of a Nerdfighter is a Decepticon.

A person who is not made of flesh and blood, but is, in fact, made of awesome.

Started by brothers John and Hank Green, as a part of the "Brotherhood 2.0" project of 2007, where John and Hank would communicate only through video blogs for an entire year. (youtube.com/vlogbrothers)

The signature move for nerdfighters is Star Trek hands (you know, the funky fingers).

Nerdfighters will be happy to know that the VlogBrothers are going on a "Tour de Nerdfighting" at some point in 2008. (papertowns.com)

Most nerdfighters desperately want to live in an imaginary (or is it) place called "Nerdfighteria" (or Nerdfightaria, depending on spelling).

(from An Abundance of Katherines, a book written by John Green)
"The fans of Brotherhood 2.0 call themselves nerdfighters. A tightknit and extraordinarily dedicated community, the nerdfighters have raised tens of thousands of dollars for charities and political campaigns, taken over the most discussed pages of youtube, and written hundreds of letters to Merriam Webster lobbying for the inclusion of the word "nerdfighter" into the dictionary."

*note: In case you couldn't tell, the term "nerd" is not used dispargingly, but is rather used as a source of pride. If one is a nerd, they should be proud!
