We're Americans, and as Americans we have a tendency to slaughter any language we come in contact with. We verbify words that shouldn't be verbificated. So yes, let's go baseballing, let's soccer it up. Right now, I'm going out parkouring, on some seriously parkourable spots. (ok, maybe that was a bit much
) We can be grammar nazis if that's what makes us happy, but we need to concede to the fact that people are going to mis-use words. All I'm saying is that as parkour grows, more and more people will be using parkour as a verb. If you want to police them all, and spend your days and nights trying to "educate" them, go for it. But you're in for a long fight. This topic will come up again, and again, and again, etc. I don't see it ever ending.
