A God among men, this title describes one who has achieved the pinnacle of getting a nut. In order to be deemed a nutzilla, one must nut, or ejaculate, 12 times in a 24 hour period. The presence of a nut witness is not required, but desirable.
Bro, I don't care if he fucks my sis, he is a Nutzilla.
