I named this by its siteswap name. I'm not very good at siteswaps, so I'll let you find a good tutorial on the Internet for that. The throwing pattern of this is the same as several tricks with different names. By throwing the balls in the same order, but changing the path they follow, you can make some tricks that look completely different from this one. Check out Right, Middle, Left, W, Take Outs, and Fake Mess for some other tricks with the siteswap 423.
