I hold the right button down when I am attacked thinking it will lower the damage I take (since your health bar travels left when you lose hp) and I hold down the left button thinking it will increase the damage done.. Well I used to think that at least, now it is a habit.. quote]
i do that too
also in rby i was told if you time the pokemon going into the pokeball you threw, while pressing and holding the b button down it makes your pokeball act like a masterball so i always hold the b button down now... i always knew it didnt tho.
