These two boys are hanging out of a tree. What else can you hang out of?
If you want to dry some wet clothes in the sun, you can hang them out of a window. If a basket of dirty clothes is really full, some of the clothes might be hanging out of the basket.
But hanging also means something else. Hanging out is what you do when you are bored and are not doing anything special. After you finish your homework, you might hang out in your house and watch TV. If you go to a friend's house and you sit and talk and don't do anything, you could say that you were hanging out. Lots of people like to go to coffee shops to hang out and read books.

The only time I watch TV is when I am really bored and have nothing else to do.
