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"

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."

sphynchronized 

When you and a best friend are so close that your Poop cycles synchronize.

Those two are inseparable. They've even sphynchronized, and you can smell them in the bathroom at the same time in an unholy marriage of Taco bell and raw sewage.

Sphincronised

To have synchronised shits with a friend

After he took his bowl prep, I found we were Sphincronised! I even had 3 shits before breakfast.
