Thanks for the input. I figured it would be a fumble, but I wasn't sure because I don't remember ever seeing something like that.
As for the Fumblerooski, I do think it is illegal, but I believe either a high school or college team did a similar play last year that was somehow within the rules.
edit to add:
I looked it up. It was apparently two years ago. It was a middle school. It wasn't really like Fumblerooski, but it was interesting. Below is the video.
