fluffy

"Fluffy" used in this way is a slang, informal, childish word and is not used in formal English. I believe it when applied to spoken discourse, it implies a high level of infantile or adolescent fatuity. The discourse of airheads is fluffy.

Once, many years ago, my buddy was over to the house, and so was a neighbors's kid, who had stomach issues, like with crones or something... Suddenly my friend turned to the kid who was sitting on the same couch, and said: kid; Did you **** your pants???
The kid said: No!, It's just a fluffy...
