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.)

I know, right?
