Good news for adults who don’t understand the latest slang kids are using on social media - Facebook will soon be offering a “Social Glossary” that covers the meaning of all the latest terms used on the site. Called neologisms, or bits of language being used by groups of people but aren’t in common use yet, Facebook has patented a software tool that can scan social chatter to find up-and-coming slang terms before they're universally adopted. The system could help improve Facebook's predictive text services, most likely the reason for the glossary, but will also help adults to figure out what the kids are all saying.
