I often see people try to sound smart by torturing metaphors. Personally, I've seen this done mainly by managers at mid-sized and large companies who are trying to explain their 'management philosophy' and by religious leaders, e.g., giving speeches at weddings.
They find some arbitrary object like melting ice cream or a paintbrush or cutting the lawn and they tell you a whole story about it. In the beginning it sounds crazy because there's no obvious relation between the thing they start talking about and the message that they get to, but it keeps the audience on the hook. People are curious about this crazy random story in the beginning, and then they probably remember it because making weird associations is a well-known memory augmentation trick.
So I'm not saying that this is always bad, and I can see why people do it, but also—maybe consider just not doing it next time you're tempted?
When I see a LinkedIn post or a blog or hear the start of a speech that starts with a completely random and crazy sounding story and leads into something that kinda makes sense but is still really random, I am annoyed. I think the kids call it cringe.
LLMs are also very good at torturing metaphors in a way that at first glance resembles good rhetoric but is somehow deeply unsatisfying, like eating the whole slab of chocolate. It's often hard to know exactly why I feel slightly nauseous after reading something that gives me the expectation of being memorable and satisfying, and ends up just being slop.
So use metaphors. Explore metaphors. Create visual mnemonics to help people remember. Tell stories. Express yourself.
But you don't need to torture a metaphor each and every time.
