I have never tried to spell the phrase "flip a youey" before.
It might be the only word I use that I have never considered spelling, so I am grateful that you included it your comment.
That said, I think you are wrong and it should be "uey", "uie," "u-ie," or any other spelling that emphasizes the "u" after which the term is named.
Also "I do not know the answer but I am sure you are wrong" is the most internetish comment I've ever made, so that's two striking experiences for me today.
