bio-baiting noun [U]
UK /ˈbaɪ.əʊ.beɪtɪŋ/ US /ˈbaɪ.oʊ.beɪtɪŋ/
writing an online dating profile that makes you seem much more interesting, attractive etc. than you really are
Like catfishing, bio-baiting involves a bit of deception – but this time it’s all about overselling your dating app bio in ways that don’t quite hold up in real life. A poll found that nearly 63 per cent admitted to feeling let down after meeting someone who didn’t live up to their carefully polished dating app profile. Ultimately, the best defence against bio-baiting is to move the conversation off the app and into real life quickly.

chatfishing noun [U]
/ˈtʃæt.fɪʃ.ɪŋ/
using AI tools to write messages to other people on dating apps
It’s a well-worn adage of the Internet age: people often aren’t what they seem to be online. But until recently, you could at least be assured that they were people. Now, though, “chatfishing,” a new wave of online deception, is taking over dating apps. Instead of “catfishing”—using an entirely fake identity—people are using artificial intelligence to help them chat up prospective love interests and secure dates.

grim-keeping noun [U]
/ˈgrɪm.kiːpɪŋ/
forming a relationship with someone based on disliking the same things
Grim-keeping flips the script on dating compatibility. Forget matching over favorite TV shows or whether you both like long walks on the beach. This trend is about uniting over the stuff you can’t stand. From universally annoying habits to oddly specific gripes, grim-keeping makes negativity the new love language.
