Used to define that creepy uncle you have who isn't really your uncle at all. He usually is an old friend of your father's, has a mustache straight out of a porno, and drives an old white van with no windows (a common variation is a van originally equipped with windows, which have now been spray-painted over).
A modern day wood nymph. This is a word that describes a girl that is most literally a force of nature. She both makes you smile and frustrates you at once. Her powers are endless.
