Here it is!!
[][][], then hold /_\
It will knock them back
They try to power up, use a finishing move like galick gun
They try to shoot lots of small ki blasts followed by a big one, reflect them and try to hit buu with the big one stunning him.
If he doesn't do one of those two things, he usually starts rushing towards you
If you catch him with square while he is still rushing and is right beside you, do the [][]/_\ combo again and repeat
From gamespot. [] means sqaure, and ?/_\ means triangle.
