shell ass 

A condition met when one refuses to wipe his ass after a messy turd for an extended period of time. The turds subsequently harden leaving the sufferer with a solid crust that mimics the appearance of a turtle's shell.

Can be effectively used for defensive purposes.

I've a kickboxing match coming up, I've got a solid case of shell ass to keep me safe.

Shell League Gulag 

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.

FUCK YOU DESTINY WHY AM I IN SHELL LEAGUE GULAG NOW
