When you fart inside a Snuggie™ and becomes trapped for later until you stand up. Similar to the Dutch Oven
I was all warm and cozy last night while I was eating chili in my Snuggie, but I ended up with a Stuffie™ by the end of the night.

The fluffy stuffy is when you hunt down a furry and become their friend. Once you have gained their trust, then you must seek their friend ship. Once they are comfortable around you, you must make plans to go to their house and have a sleep over.

Then, late at night, you take their furry fluffy skin costume and you nut in it. Once finished, rip open every single toy they have and pee in them. Therefore you have distoryed their furry pack. If the furry friend wakes up you must assert dominance. Because now you have awaked the animal in them. You must poop in their mouth so they cant speak. Before giving them the sex of their life time. Once done...

You are the alpha male.

Make sure to fuck their pet as well, no bystanders.
Best friend: you know my cousin is a furry right?
You: yeah, i gave them the fluffy stuffy last night.

Comparable to a stuffy nose, but for your nuts. All clogged up and you need to blow it in order to feel better.
