UDM 

Urban Dictionary Master, one who has the ability to access Urban Dictionary at all times and possesses the need to use it in both times of need and in times of excess.

David is definitely the UDM, I asked him what laundry limbo is and he told me in less than ten minutes.

Udmurt 

One of the most interesting minorities of Russia, this ethnic group speaks a Finno-Ugric language and has one of the most beautiful national anthems in the world. Their land is beautiful too---it's too bad hardly anyone knows about this area, because the tourist infrastructure there is in its infancy, and the russians have seemingly intractable security issues involving protecting their country against terrorists. Udmurtia's capital is Izhevsk, birthplace of the great composer Pyotr Ilyich Tchaikovsky.

The people in that small village speak Udmurt.
