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".
Mr. Tumnus is yet another word for the Perenium (bonch, gooch, taint, grundle, chode, etc).
The use of this narnia name came from scroTUM, and aNUS, hence referring to your chode as Mr. Tumnus. Giving that special area of your body a name just makes it a little more personal. Kinda like naming your junk.
The Most wanted fawn in Narnia because he had given every little kidturkish delights and had sex with them.
He is right now in Earth teaching kids at Rye and also attending North Salem High as a little turkish boy.
