Xgf is short for "ex-girlfriend." This abbreviation adds an x to the popular gf abbreviation, to denote that someone is talking about a previous girlfriend.
People may discuss their xgfs for many different reasons. However, it's usually not to say anything nice about them. For this reason, you're more likely to encounter xgf used in negative circumstances and conversations, rather than positive ones.
