Nun's finger refers to the lump on the middle finger from writing long papers with a pen. It's common among university students during their exam periods, especially MBA and medical students who have very long exams papers to write. It is thought to have come from a joke about nuns getting a similar lump, or rubbing sore from holding candles in a similar way to a pen but using them to pleasure themselves. There is also possible reference to the virginity of a finger, as the nun's finger syndrome is more common when the finger owner has not performed a great deal of intensive writing for some time.
As I am a computer programmer, I don't write with a pen any more I have a nun's finger from all my MBA exams.

When she dresses up as a dirty nun. Set up two chairs, one on each side of a slightly open door. She confesses all the dirty things she wants done to her. You then proceed to satisfy every confession.
Kelly wanted The Dirty Nun Confessional last night, so after confession I tied her face down to the bed, spanked her bottom red, raw dogged her bottom and then finished on her face. The odd thing was she wanted me dressed as Santa.

Something that is very tight in the figurative sense, ie a bunch of musicians that are so good that their performance is bang on the money.
