my code words for my wife and I are "noisey cricket" when I have my little .357 and "PC" for pocket cannon when I carry the xd45. She knows i'm always armed but she likes to guess which i'm wearing. It's our little game we play when we go out together.
Ha! This is a hoot! There was also a TV comedy, "Sledge Hammer". The detective had a 44 magnum that he talked to and slept with, but I can't recall if it had a name or not. And let's not forget Nicholas Cage's "Eleanor", the most beautiful Ford Mustang ever in "Gone in 60 Seconds".
As for me, I'm contemplating... Let's see. Bob, Dorothy, Will Robinson? I think not.
I haven't named my guns or my vehicles, except we call our surburban the "beast" because it's easier to say than suburban. My brother has a pair of matching pistols (can't remember what kind) one blued and one stainless he calls Salt and Pepper.
No names for the "weaponry"..but the code word thing is a good idea..we have been using the word "Widget"..the wife will ask if I have the widget in my pocket etc..as for the truck, no name officially, but it has been dubbed "The Guzzler" and at a whopping 5 mpg, it just seemed appropriate!
