Kid 1: "Hey, did you see that?"
Kid 2: "naaaah, what was it?"
Kid 1: "It looked like a giant chicken....with a person's face..."
Kid 2: "That sounds really weir- WTF IS THAT!!!"
Oochimama: "OOCHIMAMA!!!!"
Ok. Ohochimama is Orochimaru but twisted around. You keep the O and ro rhymes with hoe(cause we all know he is one) Then you keep the chi and instead of maru you put in mama cause thats what sasuke calls him. Thats right.
