Grieg Finger 

the index finger used to prevent sneezing (aka sternutation) by placement under the nostrils, above the top lip of the mouth. Most famously seen in Dopey, of the Seven Dwarfs. Also used by the Jupiter Group at Westerlin in their attempts to reach Jupiter by the year 3000.

I was about to sneeze all over "Slightly Off Center: Selected Works of Otto Von Grieg," when I remembered the Grieg Finger, and all was saved. I got the nostril thrill!

Greg Finger

When you shoot firearms a lot, and have other injuries to coincide, you can sometimes develop “Trigger Finger”.

Trigger Finger is also called: trigger thumb and is a condition in which a finger gets stuck in a bent position and then snaps straight.
Trigger finger occurs when the tendon in the affected finger becomes inflamed. Those most at risk include women, people with diabetes or arthritis, and people whose regular activities strain their hands.

When a male, career, shooter gets it it’s called “Greg Finger.”

Travis: “Hey Hank, did you hear about Greg getting trigger finger?”

Hank: “No? You mean he got Greg Finger, right?”

Travis: “Yup, from all that masterbating he does before going to the range.”
