Flowerskirt

A flowerskirt is a devious word used to describe an innocent-seeming person whose behaviour doesn't reflect, and is in fact opposite to, their true nature especially on topics like sex. Its double meaning refers both to the property of flowery skirts as a symboly of innocence and a skirt spread open like the petals of a flower.
