The most treasured and elusive sexual move of all time. When one is in a flirtacious situation with a woman, and brings her back to the room for some "heavy petting". When they get to the room and the woman has de-clothed, the man goes to his closet and says, "Hold on, I have something for you." He pulls out a
viking helmet and a sword, which the woman puts on. She is
sitting on the side of the bed, and the man then says, "
I'll be right back." He never comes back. The woman is alone. In a viking outfit. Hence, the "Lonely Viking".
