I think that doesn't matter so much. That you know that zap is sending sats over lightning is also something which wasn't immediately obvious. Only experience told you that that's it. Not sure if there is even a definitive definition on that? It's probably just a swarm thing.

We can now build on that swarm knowledge using zonk. Zonk is related to zap and zonk sounds as if it's a sad sound in minor / disharmonic (?), so I think you just need to explain it once to each person (like zaps) and they won't forget.

Also it's too late. I'll use zonk now haha
