From herpetology; the practise of housing two or more species of animals that may hybridize to produce "junk" offspring. This is an especially important consideration for rare and endangered species.
"You have two different species of glass frog in the same terrarium? Don't be a hybridiot!"

Term for a smug person who has an unrealistic belief in the environmental benefits of automotive hybrid technology, and acts as if their hybrid car is as ecologically friendly as a horse and buggy.
He is such a hybridiot--he actually thinks he is single-handedly reversing global warming with his Toyota Prius.
