A painful and elocutionarily debilitating medical condition originally identified among pederastic members of the Brothers Hospitallers of St. John of God, brought on by compulsive fellatio performed on unwilling minors.
A doctor's office in 1974...
Doctor: Well, Brother, what might the problem be today?
Patient: Humph-haugh-haugh-maugh-hinh.
Doctor: St. John's jaw again, is it? That's the third time this year, Brother. You really must give it a rest.
Patient: Rhaoum-haugh.
