The former guy is pretty simple example. My partner refers to as being a squid, spraying ink and making a get away.

It's been a long time and I don't remember specifics, but - we'd regularly be meeting with people from multiple different departments, and it'd be things like two people talking about testing, where it turns out one is talking about unit tests & CI and the other is talking about user testing, and you can go very far into that conversation using all the same words and meaning very different things.

A fairly simple one I've seen is "when will this be done?" - stakeholder means to ask when will it be in production; engineer hears "done" as in "my task is done" and answers about when the PR will land.
