It's a name you dimwit. Possibly a name made by parents who were 100% intoxicated and were shouting ridiculous words in Russian until they came across a word called Sardor; of course, this isn't even a word in the English dictionary. It's Russian, you melon.
In addition, the origins of the name are clearly unknown since they came from the Great Siberian forests of Russia.
Guy 1: You've seen Sardor? I've heard he's donating explosives and nukes.
Guy 2: For realz!? Great, I can now cause 9/11 all over again!
Officer 1: Hey! What are you guys talking about!?
Random Streaker: For the Soviet Union!
