FNB stands for two things men often love that women might not be too crazy about: football and beer. Guys usually text FNB to their buddies on the weekend to make sure football and beer will be present when they get together.
For example, if you are getting together with your friends on a Saturday afternoon for a college football game, you might text them, "will there be FNB?" Or, if you are attending a family gathering on a Sunday when your favorite NFL team is playing, you might proclaim, "I'm only going to Uncle Pete's party if there's FNB."
