Is "Socketed Thing That Should Not Be Of Razors" real or a bug?
Solution 1:
It's a real item; the base item is the "Thing That Should Not Be"; that is, something that's unnatural or shouldn't exist in this world. Seems appropriate for a Witch Doctor.
If it helps, the name of your particular item can be parsed as:
Socketed (prefix; adds a socket)
Thing That Should Not Be (base name)
Of Razors (suffix; adds thorns property)
Solution 2:
That looks real to me. I've never played a witch doctor, but occasionally witch doctor items drop, and they generally have crazy names like this one.
