This will plaster a website with randomly sized and positioned dickbutts. Uses an inline SVG image in order to eliminate external references.
Create a new bookmark in your browser with the content of the dickbutt.min.js file (you may use the dickbutt.js file as well, but it's not minified) as URL and prepend 'javascript:' as protocol. Click the newly created bookmark on any website to have it plastered with dickbutts.
Due to the nature of adding multiple elements to the DOM this will become noticably slower if the number of dickbutts is increased.
