An internet simplification of the phrase, "I know right," due to the misinterpretation of the words spoken with haste.
Better known as, "The rock of knowing" with the suffix of "-ite" that resembles the names of stones. (i.e. Labradorite, Malachite, Granite, Angelite, Azurite, etc.)
Adam: Man, that fruit looks delicious.
