Nope. Well sorta. My brother and I have some nicknames for various guns, but it's generally descriptive (water fowl engraving=Bird Gun). The only exception I can think of is a French shotgun named "The Dame".
I didn't know this was a thing. I've had my 95 for 10 years and so far long periods between use haven't seemed to effect it. It's definitely been a while, I'll have to take it out and test it.
