A Fiona
A Fiona is the most beautiful girl who will tell you you're ugly, then make you her best friend anyway.
My Fiona told me I had 'face hair' and 'bad posture,' then asked me to her birthday party.
My Fiona said I was 'not cute,' then sent me 500 texts about it.
My Fiona called me a 'disaster' then cried when I left her alone.
