I would imagine you would be nothing but a giant head.... or a giant mouth at that. So, you would sorta be leaning more toward the dissapear but you would still have your mouth. This is assuming that someone could also survive without the rest of their body parts, that is.
Neither. I'd turn into the Hulk. XD
That generally would be called a mess.
You would be approximately the same size, but in a bunch of chopped up pieces after they passed through your mouth. But of course there is an evil magical spell on your mouth so that you can run it without a brain or any muscles (and so you would even want to eat yourself, lol). So yeah, in the end it would be a mouth and some sludge that used to be you.
lmao i would be 2x as big haha
I would completely disappear.
I don't think you could eat yourself. :P But if you could then you would probably end up as just a head.
