A move used to inflict damage on an object/opponent. You pull your
head back and slam it forwards using the part of the skull above the forehead to strike.
Usually you hold your opponents face square with
one or two hands and bash them in the nose with your
head.
For greater damage you hold their
head with your leading hand, raise your leading foot while leaning away, then bring your leading foot back towards them in a stomping motion with the headbutt coming in right behind to gain the momentum of the stamp. This technique is used by wrestlers a lot.
Not to be confused with "butt
head".
