shitchronized 

The moment when you and a friend are texting and taking a shit at the same time.

Friend 1: "Dude are you taking a shit right now?"
Friend 2: "Yeah bro, it's super spicy."
Friend 1: "Bro, we just shitchronized."

Sphinchronized 

When 2 people's bowel movements have aligned to the same general time.

"My best friend and I have known each other so long that even our morning dumps have sphinchronized"
