The slang meaning of the term dates to the next year, 1951, when Newsweek magazine reported on its popular use as a synonym for drip or square in Detroit, Michigan. By the early 1960s, usage of the term had spread throughout the United States, and even as far as Scotland. At some point, the word took on connotations of bookishness and social ineptitude.
