The whole nomenclature thing can be a real problem and I'm as much an offender as anyone.
When I was gunsmithing in a busy retail store I often heard some very strange names for parts.
The forend of a pump action shotgun received such titles as, the pump handle, the recycler,and even the armature. Ejectors were flippers, rejectors, or, on one memorable occasion, the ejaculator.
We once had a fellow call up and speak to my friend, Pete. Pete was a transplanted Texan whose drawl got more and more Texas the longer he was away from his home state. Anyway, the conversation went something like this..
Pete: "Howdy, what can I do for ya."
Caller: "I was wondering if you had any setters."
Pete: "I'm kinda partial to Labs myself but we have a fella that raises pointers and another has Brittanys"
Caller: (pauses)"I don't know what that has to do with setters."
Pete: "Well, they're all bird dogs although some might argue the point when it comes to them setters. They ain't too popular around here."
Caller: "I'm not looking for a dog. I want the thing to set the rear sight on my .22!"
