look up any word, like the eiffel tower:
A young woman, very athletic, 16-22 that is all "girl" but wants to compete against a superior athletic guy at everything. She believes she's "tougher" than she really is but, she's so adorable making her; Fluffy Tough.
Girl: I will race you up that hill and kick your butt!!

Boy: Sweetheart, you're 5'5, 110 lbs of fluff. Don't get all "fluffy tough" on me....
