From the Card Captor Sakura English manga, "phwee" is the romanized version of the sound she makes ("Hoeeeeee..." {pronounced like ho-eeeee}). It's supposed to show surprise or confusion.
Phwee Phwee is a smart cookie!! She is quick to correct any incorrect facts and loves to do so! She enjoys reading and video games and basketball. Her thick, stick straight blonde hair is either in a low ponytail or just down and if anyone even dares to try to change that or even touch it, you're a goner!! Her calm but fun personality is entertaining and makes you happy to be her friend. She is loyal to her best friends in their ups and downs. They are long life friends, so never let them go!

Alice: Dude, I don't know! Ask my friend Phwee Phwee, I am sure she knows!
