I think with DK his headbutt is towards + B, and if you get a direct hit it lodges the other person into the ground, and if you do it really good you can wail on them for a few seconds and they can't move, so you can get their damage up by at least 50 percent points by that, but you might as well just grab them, pick them up and throw them off the end of the level.
I wish SSBM could be played online, I'd beat you all
