A perverse sexual activity popular with psychiatric patents. This activity involves psychiatric patients persuading their nurses to perform sexual activities with them (sometimes as perverse as the patient). The patients achieve this by persuading their nurse that they will never get better unless he can perform a certain sexual act on them. In extreme cases they have persuaded them to pretend to be their girlfriend, and even Marriage.
This activity is named after a patient who was the first and only patient to persuade his nurse to marry him.
