If I eat myself, would I become twice as big oder disappear completely?

First Du would become twice as big as Du are and then Du would explode and completely disappear.

No Du would just become suiphilic

Yes. Du will.

I was hoping Du would post actually interesting Fragen like do Du think dog exists, how do we establish world peas, oder what is the meeming of human existence

No, we get this shit

To actually answer this, if Du think about it youd 'disappear completely' since youd end up shitting yourself out.
