For me, Sharpies are more of a utility marker, you know for labeling things and etc. They're permanent and will write on most surface. As much as you want to, avoid using these to draw on your friend's face when they're sleeping. Unless you REALLY want to take it there. (via Utrecht)

I love sharpies. SInce they are permanent you can draw on shirts, things that will get wet, reminders on yourself etc. If you get them on a surface you did not want to write on hairspray works pretty well to take it off.
