Realted to mainy. It means you flipped out. You went bannanas, possibly in a good or bad way. You turned into Iatola Gomainy on the weight bench means you did a outrageous amount of sets or lifted an amoutn of weight you had previously never lifted. If you got into a fight and turned into Gomainy, then you damn near whooped somebody to death.
