The act of gloating, or rubbing a victory in someones face, without actually doing or saying anything. Can also be silent epeening when the person ahead in the competition will not acknowledge the other participant
Two people are playing a fighting game, one just won the game land-slide. He's doing nothing but sitting there not acknowledging the other person talking to him. "Stop your fucking Silent E-peening you faggot"
