EV Training is a special way to play Pokemon that utilises maths to maximise each of your pocket monster's statistics. Pokemon Rusty doesn't get it, even after the amazing Mr Brentalfloss expertly summarises it in song. "You're sucking the fun out."
I've never been much of a min-maxer myself, preferring to enjoy my games without having to pull out a calculator. The most mathematical I've gotten was in Funcom's Anarchy Online, the MMO where putting on a piece of advanced armour is only a large, complicated equation away.
