A word that can be used to express anything. Kind of like the word "WOW!" in english, except more useful and can be used in many different ways. Normally expressed in glee, out of sillyness, for describing something that is cool, or just as a greeting. Origins of the word, however, are unclear. Was first used by Max M. Toby M. and Bayan B. somwhere in the shcool year of 2004-2005. The word is most frequently used alone and rarely in a sentence. Is most often said in an extended fashion (see example 1). Pronounciation is somehow difficult for most people. Pronounced: WEEUWSE or WUEEWSE or WUEEUWSE depending on the occasion, length of the expression, time of day, emotion, or context used in.
