I think at this point you are inventing terminology for the sake of it. If you had pointed arrows at different ovals drawn on different parts of the club, you’d be thinking of new names for those things too.
Juggling is not a word-based activity. It’s a physical action and visual activity. There are some concepts that will spread quicker because they have a name or label, but an almost infinite number more that just aren’t that interesting or important to enough people for a name to stick or matter at all.
I do workshops with just two clubs, focusing on squeeze catches and multiplexes. In that workshop I’m using different names for the different parts of the clubs all the time, and nobody has ever been confused about what I mean because I’m also demonstrating at the same time. When someone has a question, they might use different terminology, but that doesn’t matter, because they too have the clubs in the hand.
I can’t think how tedious it would be to have to explain these tricks and techniques using just words written out in full, with no pictures, video, demonstration, illustration or anything else.
I’d just say “Hold it like this:”
“Throw them and catch them like this:”
Not a real trick, of course.
Ever more specific language only helps up to a point. In 99% of cases saying “catch the club by the wrong end” is totally clear, with no need for “bell” or “cone” or “bulb” or “neck” or anything else. When more precision is needed, you are probably in a situation where showing is more practical than more specific terminology.
I suggest we pick our “new terminology” battles for situations where there are current misunderstandings or problematic disagreements.
