This happens on a discord server called Shell League, which is full of socially awkward teenagers where they go when having existential despair. The gulag of this server happens when a bitch ass retard mod puts you on time out for only being underage or attempting to locate an underage child to fuck for fun. Also can have discord sex with children if lazy enough.

A Magic Shell shit is a shit that comes out as a thick brown liquid, but hardens into a solid when it hits the cold toilet water. Usually comes out shaped like a Dairy Queen chocolate cone. This heated liquid usually burns your asshole coming out.
