Stands for "Not actual boyfriend". For a situation where the couple is between the "friends with benefits" and "official" stage. Either one or both of them are not comfortable with being called "official", yet everyone knows they are seeing each other, they are exclusive, and they do some couple-like things. They may not yet go on dates, however.
"Hey Karissa, did your nab finally decide he wants the label even though it's been 3 months?"
