What is "bragster"

Bragster was a global social networking and video sharing website on which users dare each other to perform stunts and tasks. The website name stems from the 'Bragging Rights' which are earned on the site. The company is based in London, England. The majority of the content is user generated, although some branded videos from companies such as Tango, Adidas and Wizards of the Coast have been broadcast on the site. The site is designed to be a more niche alternative to other social networking websites. In February 2010 Bragster was acquired by Guinness World Records.
