The act of traversal over many Wikipedia pages, typically to pages that are contained in the initial page you went to read.
Today i was wikihopping so much that i started reading a page on Samuel Clemens and ended up on a reading a page on the war atrocities by Japan during the Second Sino-Japanese war. (Via Mark Twain->Vivisection->Human Experimentation-> Second Sino-Japanese War)
