When I was in the 7th Grade, I used to splash pink glitter on my cheeks every day during school. I thought I was cool for doing that....
Today, I use purple, light pink, and light blue glitter for my eyes. I also have a silver one, but for my lips. I use an indigo opalescent one mostly; it's from Manic Panic. They have endless supply of glitters and different types, depending where and how you want to wear them.
Urban Decay also sells Heavy Metal Glitter Eyeliner, which is a wonderful product. I have Air Guitar (light blue) and Pyrotechnics (glittery white). They will not slick or fade unless you take it off, and even then, it might be difficult to do so. All in all, it's a must have for glitter lovers.
