It became extremely popular, as did slam dancing and other forms of punk dancing, in the mainstream a few years after it started. This is true for most things punk and true metal did.
One of the clearest examples of this was performed by a crust punk band with a cult following for the late 90s and early 2000s called R.A.M.B.O. where they would encourage the crowd to dress up as either protestors or cops and stage a mock riot. The two sides would form up and then 'wall o death!' each other.
