A inbred human being with little to no common sense. A wohltmann has no known skills and thus must fuck strangers with no personal interest vested in it to obtain goods and services. The intelligence of a wohltmann has not been successfully measured but is believed to be less than that of a retarded earthworm. If you encounter a wohltmann the best thing to do is bash it in the head and bury it...unless you're horny. Then fuck it, bash it in the head, and bury it.
That wohltmann in my physics class is so dumb, but she puts out.
