adj. Descriptive of an uphill gardener who's so far in the closet he's found Narnia, taken out a mortgage there and spends his days fraternising with the local populace.
"I don't care if he was married to the bird off Dawson's Creek, that Tom Cruise is so far in the closet he's on first name terms with Mr Tumnus".
Urbandictionary told you to look this up. So now you have. Why? You're a smartass. Or a blond/blonde. Either way, this is a total waste of your time and you've just lost about 4 minutes of your life from this useless piece of crap.
Congratulations.
