I love the fact that in the latest edition of the Tony Hawk Pro Skater video game, the hot new tweak is the addition of a new ability ... the "Spinal Transfer".

The main gameplay change is the addition of spine transfers. This lets you reorient your skater in midair so that you can go up one side of a quarterpipe and down the other. It also works for getting out of pools and halfpipes, getting up onto high ledges, and, much like the bail button in Aggressive Inline, saving yourself from wrecking when you accidentally fly off the side of a ramp.

No wonder most parents haven't got the vaguest clue what the hell their teenage kids are talking about.
