A person of dual sissiness. This is actually a combination word. The person this word describes is not only a wuss, he is part wimp and part puss. Originally first heard by Damone in Fast Times at Ridgemont High.
Invented in the summer of 1964 by an eight year old San Diego elementary school Boy named Don who needed to find a new name that none of the bullies would recognize. The popular insult names at that time were Wimpy, from the "Popeye The Sailer" cartoon and Pussy from the obvious. Wussy and Wuss kept them confused for a short time and gave the abused a short victory over the bullies. In the beginning Don actually had them conviced it was a compliment. By 1972 it had become a real comon word at Clairemont High School and was later momorialized in the 1982 movie "Fast Times at Ridgemont High" that characterized those people at Clairemont High.
