A quick search for the acronym “YBF” reveals that there are several different meanings. Although it can be used in many ways, one seems to be the most widely accepted. It can be used in regular conversation or it can be used as a way to close a letter or message.

This word can be used by anybody in most situations. It is more likely to to be used by younger people that are probably female. If an older male were to use “YBF,” it may be in a joking manner.
