But what's the charge about? Touching someone's ass without permission is a long way away from forcible rape.

Took some clicking, but this is the best we got so far:

Details of the alleged assault weren’t included in court documents.

I don’t really know enough about Mike Smith to have expected it, I guess. Surprising and sad from my perspective.

So, in your mind he's guilty of what exactly? Because I couldn't find an article outlining the details or circumstances. Nothing but the fact that he's been charged.
