THIS grinds my gears......

I don't know if it is because I am a physicist or because English is not my first language, but to me when I hear chain stretch I think of the side plates getting longer, like when you stretch dough. Of course that is definitely not what happens as the chain wears.

And as for "chain suck", we really must stop using this misleading term.

Why misleading, the chain gets "sucked" back onto the chainring by the hook like worn teeth. I think it is a good image.

It misleads people into thinking that the underlying mechanism is suction. We can't have that.
Suction: the act of removing air from a space resulting in a lower pressure in that space, either causing liquid, gases, or other substances to enter, or causing two surfaces to stick together: https://dictionary.cambridge.org/dictionary/english/suction

"Chain slap" is another one. I think this probably Ok.

Yes, I can't disagree with that. Chain hook(ing) instead?

Yes - just like bread dough.

Found this in our discussion in 2017: https://www.cyclechat.net/threads/when-to-replace-cassette.215443/
And this was useful (imo) from @Yellow Saddle : https://www.cyclechat.net/threads/why-a-worn-cassette-cannot-damage-a-new-chain.255700/
No pictures though

if your chain separates or breaks under tension is it permissible to use the term "snapped"

I recommended the use of "parts". This avoids "separated" which could easily imply deliberate action, and is more useful than "breaks" because it describes the effect of failure.

I still can't believe that there are people out there who take shortcuts with chain maintenance. Do it properly!

I never shirk this Method. Often taking an Emergency 1/2 days Holiday at work upon arrival - so I can have a freshly lubed chain for the commute home…..
