When you eat dirt for the first time and leave your family to build a shack in the woods

what began as an uneducated, ignorant form of "excuse me," the beauty bitches of richmond, va started using the term in excess after hearing it multiple times a day at their mutual place of beauty employment.

Although it has probably been accidentally and infrequently used for centuries by uneducated english speakers, this degraded form of "excuse me" came into widespread use in the middle class area of the city of chicopee circa 1993. Scott Reed and his friends apparantly recorded the expression for the first time while creating sounds to import into a computer game they were working on. It has since gone into history as an expression used when immitating a retarded person. The expression can still be heard in it's original dialect in the local "food bag" store near the Chicopee Country Club. The Slushy Artist still chants "Scu me...scu me....scu me" each and every time he pulls the slushy lever.
