I was looking at all the codes for smilies on Facebook chat and there’s a relatively new one where you type :42: and it comes up with a random 42 with a red background. What does this mean?
it means 42
It’s a jokey reference to a book: The Hitchhikers Guide to the Galaxy by Douglas Adams. It means “the ultimate answer to life, the universe, and everything.” If you use it, it also means you are a fan of Douglas Adams and his books.
