When you get up in the middle of the night to go to bathroom, you urinate on the porcelain inside the toilet, instead of directly on the water to avoid making that 'sploshing sound.' This is done to avoid waking up your spouse or a roommate.
"I heard you get up last night and go to the bathroom"

Porcelain cinnamon is what's left on the back of the toilet bowl when a lad in front of you wipes his bum when he finishes pooping. It's a mixture of toilet paper, feces, and butt hair. The position one must get in to wipe adequately often lends itself to quite a bit of the sediment left behind on the seat. One must always be wary of the porcelain cinnamon prior to sitting down on the bowl themselves.
The lad in front of me left quite a bit of porcelain cinnamon behind, so I'm going to need to clean off this toilet seat before I sit down.
