We can't talk about it. However you can find it by googling it.
Just don't overuse it...Otherwise the host of game will ban you from his/her game.

Although some glitches are actually tricks.
For example. Makin Hay Hut isn't glitch. It's simple trick you just need to know how to do it
Although walking outside the map is glitch but it's hard to control ur character since it'll ripple the game screen ^__^
Hay Hut and walk outside Map is one trick ALL TOGETHER. But walk outside is glitch.
