I have the same idea with hattersin. It's like taunts before battle if you play games like tekken or soul calibur or tekken vs streetfighter, etc.
But the name of the item is "kiai" which means a battle cry before a match which you usually hear from karate, taekwondo, judo or any martial arts where fighters shout not taunt/dialogue.
i wonder if it could also be made as an item for taunting, speech, etc.. If so, then this suggestion would be nice.
