Is it really verbing?

Just listening to Wisconsin Public Radio and they're doing a report on the group Soulforce touring colleges that openly discriminate against gays and lesbians. (The bulk of the story is available here, just scroll down some, but not the crucial chunk below, at least not yet.)

WPR talks to folks at a small religious college (I didn't catch which one) and a woman student said, I'm pretty sure, "It's a sin to gay …". There was surely no rapid speech thing going on, and she sure didn't sound like she'd made a mistake. Sounds utterly impossible to me. I mean, *It's not easy greening.

Any idea what's going on here?
