The appearance on an electrocardiogram (ECG) of a run of ventricular tachycardia that resembles a group of hooded figures praying in succession. This usually means the patient is in acute cardiac distress and needs immediate medical care.
I was doing vitals on my patient the other night and saw the marching nuns roll across the EKG. I hit the code alarm faster than I've ever done anything in my life.

Get the Nunmug. An expression of exasperated confusion, being unable to explain logically the good fortune of one’s present circumstance by insinuating the performance of something karmically exceptional in a past life.
To get such a partner; so attractive, thoughtful, and who contributes so much, it must have been a whole bus full of nuns.
