A bell-shaped systems-type guy. You know the type, narrow shoulders and enormous ass. They sit around all day talking about how smart and creative they are. In fact, they usually only create network hang-ups and little brown replicas of themselves in the toilets.
Terry Thiel is the biggest tweedledump I've ever seen! He left one of his clones in the toilet!
Get the tweedledump mug.
The distinctive sound of waste excretion originating from a tribe of giant pear-like beings. Phrases such as, "God I love downloading" are quite frequent in tweedledumping grounds. Tweedledumps are normally very painful to the fat waste of flesh and commonly go by the name Ben Holder or Mikael Lucas.
Ben Holder likes to pretend that Mikael Lucas is the last Tweedledumper, the excitement causes arousal and soon the two are joined in the bliss of a thousand tweedledumps.

See Also: Ben Holder is a fat fuck, Ben Holder is an inbred loser, Ben Holder is going to lose his fat fucking limbs to diabetes and blame it on genetics and not his fatass diet, fat.

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.
