1. A Person who, being unable to express his anger through physical violence (owning to their physical weakness, lack of bravery and/or conviction in real life), instead manifests said emotions through the text-based medium of the internet, usually in the form of aggressive writing that the Keyboard Warrior would not (for reasons previously mentioned) be able to give form to in real life.
2. The term is a combination of the word 'keyboard' (the main tool by which the person expresses his/her latent rage) and 'warrior' (due to the warrior-like aggression, tendency towards violence, headstrong nature and propensity towards brute force as a means of resolving conflict rather than more subtle means dependant on finesse).
3. The Keyboard Warrior seeks to use the power imbued in his 'weapon' to effect death and destruction (in a strictly-metaphorical sense) upon his foes (other virtual identities he has encountered on the internet). In essence, the keyboard (ie. text input ability) allows the keyboard warrior to manifest his true warrior nature in a safe and removed environment, from which no real-life repercussions .
4. Keyboard Warriors are generally identified by unneccessary rage in their written communications, and are regarded as 'losers' by other virtual identities on the internet.

a keyboard warrior is generally someone that is spending more time behind the keyboard (on the internet) than anywhere else. he will not quickly send a text message for a little question, he will not call you for anything - he will send PMs on forums and emails. the keyboard warrior is someone that asks many (often complete and utterly unneccesary) questions all the time on message boards and email, as if he had no logic himself to combine and get his answers from.

A sad person who gets a kick out goading an innocent person then calling this person a keyboard warrior! When in actual fact the person being goaded is just reacting to being called something derogatory and\or insulting!

Usually this is done through the text-based medium of the internet and usually under the cover of humour and usually split between threads or conversations to mask the accusation.

A person who is such a wuss that he can only act all bolshie and tough by text message, but not by phone and most certainly not face-to-face

An ignorant person who knows little about the finer points of MMA techniques and skills, who has never been in combat but sits on the couch as a spectator and with supreme confidence gives his expert opinions (actually an idiot's view) to anyone who will listen. Couch warriors also give people the benefit of their profound ignorance by making stupid text comments on websites that cover MMA news.

When a text (anything with words, whether it be spoken or written) has a topic or subject that a group of words relate to. If a passage of writing included the words
"heart", "flower", "love", "music", "passion" the semantic field would most likely be considered 'love'. A semantic field of love. Also the lexis may be referred to as "flowery" or even femnine

On a MUSH (sort of like a text-based MMO), Consensual Roleplay means that your character will not get into any sticky wickets that you do not want him/her to get in. You control your destiny, and if Quickswitch wants to murder you with his space-puma jaws, you can say no. Alternately, you can't touch Alpha Q in the swimsuit area without his written permission.
