shartfluff 

an accidental shit that comes out when you have gas but it's fluffy and soft on the anus.

I have some shartfluff in my underwear. It's disgusting but suspiciously delicious.

Shartflurping 

The act of sharting in a pair of unworn panties and tying them to a high up anchor point to then bite and hang from them by your teeth.

Hey babe, I was thinking maybe we mix it up for our first anniversary and go shartflurping. Maybe if we have a good time we can make it a tradition!
