What's baku-canceling?

I’m starting to take up A/K/N groove Joe and I need to know what baku-canceling is. What it is used for and how do I do it?

supposedly you can cancel one into another and repeat, but of course its highly unlikely you will pull it off, and even more unlikely in a match. At tops I’ve seen it combo 3 times, its not easy, good luck.

Alright then, I’ll try it out. Thanks a lot

wtf this is some random crazy glitch. is there any more info on it? why does it happen?

I know a couple of characters have mash specials that cancel with PPP/KKK. Chang’s ball can be instant in the same way, but I don’t know if it allows for comboing like Joe’s.
