The cute, romantic scene in a fanfiction. It can range from hand holding to cuddling to kissing. This type of fluff can make the weak fangirl/boy squeal.

The fluffy marshmallow gooey stuff that you get from the store.
Usually from the creators of the regular marshmallow unless you buy the great value kind like a cheap ass. It's really good, and can be easily addictive if you have too much if it.

The equivalent of ‘resting bitch face’ for an animal. Often seen on cats when it looks like they are angry, irritated, or about to attack you, but they’re actually relaxed and it’s just their face.
“Omg your cat is so angry, I’m scared it will attack me”
“Nah they’re all good, it’s just their resting fluff face, they are super friendly really!”
