In the 1910s and early 1920s, a "Jellybean" or "Jelly-Bean" was a young man who dressed stylishly to attract women but had little else to recommend him, similar to the older terms dandy and fop and the slightly later drugstore cowboy. F. Scott Fitzgerald wrote a story about such a character, The Jelly-Bean, in 1920.
