It's a pipe thread, try tightening it slightly then loosen. Also might find a square socket to get a good bite on the plug.

if you can get a square socket on it as BC59 suggested, you might try an impact. A lot of times, the blows from an impact will knock things loose that don't want to come loose by brute force.

Don't think it's pipe thread, the ones I've run across are straight thread with a gasket.
On stuck ones a pair of Knipex Plier Wrench have worked great for me.
