hypoxicrite
Someone whose blood-oxygen levels are dangerously low due to all of his hollering, wheezing, snorting, and otherwise hyperventilating at others about their supposed faults/shortcomings, when he himself either does the very same (or far worse) things.
Gerald Strickland was a prime example of a hypoxicrite --- he loudly reprimanded anyone who either drank or didn't perform up to his standards ("Slacker!"), yet he himself was a closet-alcoholic and didn't even take proper steps to ensure the safety of the students under his supervision.
