vixen

I'm a little stuck... Click here to teach me more about this clue!

'foxy lady' is the definition.
(I've seen this in another clue)

I don't understand the rest of the clue.

(Other definitions for vixen that I've seen before include "A foxy lady?" , "Female fox - spiteful woman" , "She-fox" , "Mate of 2" , "Cunning Little creature (Janacek)" .)

I've seen this clue in The Guardian.
