I don't think that the poll is a true representation, to be honest. I think it's fair to say that most clients like owo, and therefore, if girls can be convinced that a GFE must include owo, they would do so.
Ergo, I don't think the poll really asks whether people truly think a gfe includes owo, but rather, if they want it to include owo.
As I say, gfe has always meant kissing/ cuddling, Look it up and thats what is says.
So I don't know why anyone would think it means owo...
