A Southern Michigan Tradition, developed by school of choice pupils, where under the circumstance that angsty teen rock is heard by these pupils, an outrageous headbanging and fist throwing session occurs. This usually lasts for the length of the song; unless it is not appealing. In recent weeks, the slam dancing ritual has been taken up by well-known celebrity, Paul Walker, and his faithfuls. This trend will surely become a national craze without a shadow of a doubt.
Dave had to stop his car because Andrew and Damon were slam dancing so violently, that the car was shaking uncontrollably.
