There are so many ways to be a fox.
For a lady then mascara, a feather boa, and an inviting look is enough, but any person of any age or sex who's being cunning is being foxy.
A time-traveller from several hundred years ago can be a fox simply by being drunk.
A barrel of beer (The Word Den does have some very odd readers)is foxed when it's gone sour; a fish is foxed when it's stupefied; a horse is foxed when it's had its ears trimmed; a book is foxed when its pages are marked with brown spots; and a shoe is foxed when it's had its uppers repaired, possibly with decorative strips of leather.
If you're not a barrel of beer, a fish, a horse, a book or a shoe, then you can always do an Australian fox, which will mean either to pursue someone stealthily, or to chase and retrieve a ball.
I think I'll go with the chasing-a-ball option, myself.
