Megaflip
It's a hard glitch to do, really. While holding Z+R, roll at an enemy attack and backflip at the same time the enemy hits you; if done correctly, you should fly backwards from the attack and take no damage.
Tips
+Try to feel the rhythm of the attack from the enemy, in this case a Deku Baba. I roll after the second or third click of it's mouth, and based on where it's neck is bent is when I backflip. It's tricky.
+Practice where failure won't set you back, or where you can keep trying in rapid succession.
+If you're on an emulator, make a save state in the right position so you can just practice rolling and backflipping.
