This is when two Canadians fist-fight. Due to maple syrup content of the Canadians, the hands become intertwined and stuck together. The Canadian Kangaroo cannot be separated, and it continues to grow and collect more Canadians.
Watch out for the Canadian Kangaroo, once it touches you, you can't get unstuck. If I were you, I would wear a lot of KY Jelly all over your body so you can slither away.
