Using a Head Butt (Ouch?)

[Shiv]

I think it is the best thing to do when someone grabs you from behind, or wants to strangle you from behind. I wouldnt use it unless I saw no other way though. ( the frontal one).

I think if you wanted to use the frontal headbutt, then you would want to make sure that you have some control over the opponent's head movement, just to be safe from him cramming his crown into yours.
