Knowing the only reason you graduated from high school and or college was because of Wikipedia.
Wiki's remorse could also be a feeling of guilt. Almost as if you cheated because you used Wikipedia and it made the assignment so much more easier.
(Wiki remorse is also known as "wiki's remorse" or "Wikipedia remorse".)
On graduation day the valedictorian was giving her speech about how she spent long hours and days at the library researching for her 15 page report on The Holocaust, and how hard work pays off. While Max thought about how he basically just paraphrased the whole Wikipedia article on the Holocaust. Then he started feeling like crap and having wiki remorse for not putting any effort into his work .
