1 definition by Sir Gwindel
A subtype of intrepid entomologist known to bring equal parts enlightenment, enigma, and randomness to a conversation. Often seen tending to the world's smallest zoo. They have been known to irresponsibly catch and raise what are, pound for pound, the most vicious and dangerous predators on the planet. Often the beasts are released back among the unsuspecting populace after reaching maturity. Rumored to have an evil parallel universe counterpart hidden in our dimension.
The entomologist returned from the jungle expedition with new specimens of rare carnivores for his collection. That person probably qualifies as a Hennen.
