Butthurt is an online slang term used to describe a strongly negative or overemotional response. It is used to draw attention to a person who shows signs of being irritated due to a perceived insult, an unfavorable situation, or a lack of decent communication. On occasions, it can be also used to describe unreasonable users behaviors without an apparent explanation.
The term “butthurt” originates from spanking, the act of striking the buttocks of another person, which is often seen as a method of punishing a child. Though some cultures view this as an acceptable form of discipline, it can be interpreted as abusive corporal punishment. Online, one of the earliest archived mentions of “butthurt” appeared in a 1998 comment posted on the website of Swiss surrealist painter H. R. Giger.
"Hollywood has tossed Giger for more talented artists, and even those artist who can emulate his style, without the tears and the hurt butts. If giger reads this I would be amazed, not only that he can comprehend a bunch of letters placed into groups and spaced randomly to create words which in turn create sentances, but that he can even UNDERSTAND the INTERNET! GIGER is LAME. all he can do is rely on his ALIEN paintings to make him famous! Well I used to be impressed until I read all this BUTTHURT he has been going through. Oh poor baby Giger."
The comment was left by a poster named Doug in responding to Giger’s grievance over not being credited as a designer for sequel titles in the Aliens franchise. In the original 1979 film Alien, Giger based the extraterrestrial monsters after one of his 1976 paintings, Necronom IV.

The Butthurt Form is a form listing certain points that may have caused butthurt, commonly used to mock people who are showing clear signs of butthurt. In the beginning of April 2012, the online group Anonymous used the butthurt form to fight a proposed Internet censorship bill in Arizona that would criminalize digital speech intended to "annoy, offend, terrify, threaten, intimidate, or harass" others. Twitter account @YourAnonNews encouraged residents to fax a copy of the form to the state's Governor Jan Brewer in protest of the law's wording. While the bill was signed into law on May 14th, 2012, it was amended to remove "annoy" and "offend" from the text. This story, and the Butthurt Form protest, was covered by RT.com, the Phoenix New Times and Techspy.
