A girl who is into sterotypically girly things, such as pink, unicorns, ribbons, fashion, makeup, etc.
I can tell you who isn't a girl girl. Tex, from the popular web series Red Vs. Blue is NOT a girl girl.

An It Girl, is a girl that 'everyone' wants to be, but being an It Girl, means, sucking every guys cock, being the shires slut, and being put on the spit, at least once a week. so in the end, no one wants to be the It Girl, no one wants to know the It Girl, the It Girl is the little girl in the corner, full of all kinds of sexually transmitted infections (STI's).
All the little girls that dress like a slut, act like a slut, and be like a slut. there the ones that end up like that. It Girl.

Get the It Girlmug. Grinned in real life. Because most people don't actually "laugh out loud" when saying "lol". We "Grin in real life".
I can't think of an example, I don't know why lol. Wait a second, that's perfect. I didn't "laugh out loud" while typing that, I 'girl.' I(Grinned in real life.)
