After ejaculating into one's own hand. You then wind up, as a pitcher would, and throw your seed at a woman, hopefully hitting her right in the face. Named after the MLB Pitcher Hideo Nomo who has a famous windup.
After that guy beat off in his hand he threw it at that girl and nailed her in the face. Wow, I can't believe he Hideo Nomo'd her.
