How does a boy hump a girl?

Well, technically, you can hump a girl anywhere you want. Most people go the traditional route and hump them in the reproductive organ. However, there are some select few that like to hump a girl in the anus. Others like to hump them in the mouths, which is probably more commonplace than humping in the anus. I've never heard of guys humping girls in the eye sockets or ears, but in light of the twisted nature of the youth today, I wouldn't be surprised.
