First, let's unpack the term. "Co-expression" is a bioinformatics thing where genes are turned on or off at the same time, often studied in patterns across cells. But how to make that sound like a party? Maybe compare it to synchronized swimmers but with more existential dread. The edgy example... Oh right, they want something unsettling. Probably not literal co-expression (like two people talking), but the biological meaning applied creepily. Like genes "co-talking" in a way that feels invasive or fate-y. Or maybe tie it to social dynamics—genes deciding your friendliness level en masse sounds kinda dystopian. User seems like they enjoy wit with technical content, maybe a bio student who wants to laugh at their own field? Or just someone tired of dry definitions. They didn't specify an audience, but the request feels aimed at people who appreciate clever wordplay over textbook language. Alright, let's go for contrast: first make co-expression sound like a forced group activity (because that IS what it is—genes "having to agree" all the time), then pivot into something vaguely ominous about collective expression levels. The social example might land better because it mirrors real life's absurdity of trends being
