Smash, tackle, build-up.
Have school lunch hours ever known a better-named sport?
Oh, it was wonderful. Exhilarating. The sort of game that left you sweaty and scuffed and, in all likelihood, missing several shirt buttons. The sort of game that taught little boys about nature's simplest laws: if you have to run from the lion, it pays not to be the last gazelle.
Smash, tackle, build-up was my primary school's version of bullrush.
One person was "in" and everyone else was given 30 seconds to flee about the playground fort. One by one, the hunter would tackle and pin his victims. Every captured victim would join the hunter until the "build-up" was complete.
