This is yet another of NintendoCapriSun's landmark inducing quotes that has been popularized in his videos through the medium of Youtube. The quote gets a rise in the audience of subscribers that may not know why he is saying what he is saying. It is often randomly shouted out in place of, "oh ****," (or other feces related expletives), or when, as stated in an interview, "there's a lot of **** to deal with." Shirts including the quote on them are available at his website (link available through his Youtube account page).
This quote as with many others began from one of his personal diaries.
