upsidedown muffin 

a) (cute definition): a girl strictly between the ages of 13-22 who is virgin and who does handstands completely naked in her bedroom, simply f-sag or to impress her bf

b) (very offensive): a promiscuous teen girl who behaves hentai both privately and publicly

if per definion b) your gf is an upsidedown muffin, you may have a problem
