I am afraid you are "shit out of luck" on this one. Loli is a specific genre, derived from "Lolicon" which has some of it's origin in the "Lolita" novel.Though it specifically refers to the sexual content featuring young girls.
Great sources. >.> But regardless, if you would scroll down one on the urbandictionary link, you would see that one definition of it is "A prepubescent girl; especially in Japanese anime/manga."
And while loli is usually referring to sexual things, it does not always have to be sexual.
