Gaelic version of Helen, meaning "light." Any expectant mother considering naming her daughter Eileen should recognize the likelihood that the song "Come On Eileen" will remain in the popular imagination and on shitty radio stations for years to come, meaning young Eileen will most likely learn what it means to "come" on someone, thanks to a pervy kid in her seventh grade homeroom.
"Who hasn't come on Eileen?"
