WTFPL is a permissive free software license, compatible with the GNU GPL. As a public domain like license, the WTFPL is essentially the same as dedication to the public domain. It allows redistribution and modification of the work under any terms. The title is an abbreviation of "Do What The Fuck You Want To Public License".
The WTFPL intends to be a permissive, public-domain-like license. The license is not a copyleft license. The license differs from public domain in that an author can use it even if they do not necessarily have the ability to place their work in the public domain according to their local laws.[failed verification]
The WTFPL does not include a no-warranty disclaimer, unlike other permissive licenses, such as the MIT License. Though the WTFPL is untested in court, the official website offers a disclaimer to be used in software source code.[better source needed]
The text of Version 2, the most current version of the license, written by Sam Hocevar:
DO WHAT THE FUCK YOU WANT TO PUBLIC LICENSE Version 2, December 2004 Copyright (C) 2004 Sam Hocevar <email@example.com> Everyone is permitted to copy and distribute verbatim or modified copies of this license document, and changing it is allowed as long as the name is changed. DO WHAT THE FUCK YOU WANT TO PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. You just DO WHAT THE FUCK YOU WANT TO.
do What The Fuck you want to Public License Version 1.0, March 2000 Copyright (C) 2000 Banlu Kemiyatorn (]d). 136 Nives 7 Jangwattana 14 Laksi Bangkok Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Ok, the purpose of this license is simple and you just DO WHAT THE FUCK YOU WANT TO.
To apply the WTFPL to a creative work the author of the work should add a copy of the terms of the license version they wish to use alongside or near the work with which the license is applied. The name of the author named in the license should not be changed unless the name of the license is changed as well—in which case a new version is thereby created.
The WTFPL is not in wide use among open-source software projects; according to Black Duck Software, the WTFPL is used by less than one percent of open-source projects. Examples include the OpenStreetMap Potlatch online editor, the video game Liero (version 1.36) and MediaWiki extensions. More than 4,000 Wikimedia Commons files and more than 24,000 Projects on GitHub were published under the terms of the WTFPL.
The license was confirmed as a GPL-compatible free software license by the Free Software Foundation, but its use is "not recommended". In 2009, the Open Source Initiative chose not to approve the license as an open-source license due to redundancy with the Fair License, saying:
It's no different from dedication to the public domain. Author has submitted license approval request – author is free to make public domain dedication. Although he agrees with the recommendation, Mr. Michlmayr notes that public domain doesn't exist in Europe. Recommend: Reject.
Mr. Michlmayr did not agree with the reasons cited for possible rejection of the WFTPL license since public domain doesn't exist in Europe. [...] Mr. Michlmayr moved that we reject the WFTPL as redundant to the Fair License.
Some software authors have said that the license is not very serious; forks have tried to address wording ambiguity and liability concerns. OSI founding president Eric S. Raymond interpreted the license as written satire against the restrictions of the GPL and other software licenses; WTFPL version 2 author Sam Hocevar later confirmed that the WTFPL is a parody of the GPL. Free-culture activist Nina Paley said she considered the WTFPL a free license for cultural works.

There are at least two not very serious licenses which have essentially the same meaning as public domain. I'm talking about the Beerware license and WTFPL ('Do What The Fuck You Want To' license). I really like these because they pretty well represent my opinion about the legalese bullshit that most licenses are so full of.

It’s even clearer that the Do What the Fuck You Want To Public License is a satire. The author is one of those who thinks the Free Software Foundation has traduced the word 'free' by hedging the GNU General Public License about with restrictions and boobytraps in the name of 'freedom' – and he’s got an issue or two with BSD as well. He is poking fun at both camps, not gently at all. His page about the WTFPL is funny-because-it’s-true hilarious, and I admit that I feel a sneaking temptation to start using it myself.

The WTFPL is a parody of the GPL, which has a similar copyright header and list of permissions to modify (i.e. none), see for instance gnu.org/licenses/gpl-3.0.en.html. The purpose of the WTFPL wording is to give more freedom than the GPL does.
