A nefarious sex act in which one partner karate chops the other in the trachea causing him or her to make involuntary walrus like noises. While the victim gasps and gurgles for their life, the shuffler takes advantage of his or her disadvantageous state, vengefully eating out the vulnerable and pulsating asshole of their victim, to the sweet sweet sound of walrus music at the sea shore.
I had to buy a turtle neck for my old lady to cover up her walrus shuffle marks. I feel shame and pride at the same time. I never thought I'd have to pay money for a turtleneck...ever.
