A playoff fan is a sports fan who has no interest in a sport or a team during the regular season. But come playoff time, that same fan is transformed into the biggest diehard fan you have ever seen.
Bob did not watch one Laker's game all season, but now that they are in the playoffs, his car is decked out in 100 Lakers flags. What a playoff fan.
