This word originated when it was an amusing typo of the word 'bloody' while being used as: "I have no bloody clue." "I have no clooby clue." It has since then become a sort of insult or filler word. It can be used almost anywhere. It's a noun, verb, adjective, everything all in one!
n. A screenshot fabricated by a company to misrepresent the graphics of a game; a combination of the wordsbullshit and screenshot.
