Xbf is short for "ex-boyfriend." This abbreviation adds an x to the popular bf abbreviation, to denote that someone is talking about a previous boyfriend.
People may discuss their xbfs for a variety of reasons, but usually, it's not to say anything nice about them. For this reason, you're more likely to encounter xbf in negative circumstances and conversations, rather than positive ones.
