"roflsup" is a colloquial term adopted by the rUcKuS peoples who inhabited the northeastern region of the United States in the early twenty-first century. As with many languages, it is often very difficult to discern an exact definition for this term, but its closest meaning in English is, "Hey, look at this!"

It is a tragic fact of history that even the greatest civilizations die out before they are truly capable of reaching their maximum potentials as societies; the Mayans, the Incans, and the Aztecs are fantastic examples of this tragic fact. The rUcKuS peoples are no exception.
