A bell-shaped systems-type guy. You know the type, narrow shoulders and enormous posterior. Tweedledumps do little more than talk about how intelligent and creative they are. In fact, they usually only create network hang-ups and little brown replicas of themselves in the toilets.
That tweedledump, Terry Thiel, left one of his clones in the toilet.
