Wait, does this apply to real life as well? I mean, it's definitely cool in games and all, but I get a kick (no pun intended... aw, what the heck. Sure.) out of doing it in real life when I get the chance. Me and my friends used to try to wall-run on a rally wall at the tennis court when we'd go down to the park in sixth/seventh grade. And then some old dude across the road would periodically tell us to knock it off (no, wait, I think it was leaning on the net that ticked him off...).
