This is my first teapot riddle so hopefully all goes well. I am sure most people know the deal but for any who doesn't, there is one word with two or more meanings (two teapots). Try and figure out the word from these hints:
The first teapot is kinda like a square,
While the second teapot is daring beyond compare.
Teapot number one can contain all sorts of things,
But teapot number two is contained in a ring.
Finally, teapot one can help you move so you get it all done.
Whereas teapot two is a way of moving that can be lots of fun.
What am I?
