Firstly, when I say football, I am not referring to the game where people try to propel a spherical object with their foot- hence football.
Rather, this game is closer to the American version of the sport, where huge musclebound gladiators enact a fusion of chess, war and ballet whilst hitting each other with heavily reinforced plastic. Hence football.
Take away the chess, ballet and plastic and you've got gnomeball, where tackling your opponent basically means wacking them as hard as you can.
And with gnomes being such good-hearted little creatures, they do at least have the decency to point out that they're about to hit you. Now you'd never get that from Warren Sapp.
