A person who is supportive of and enthusiastic about a sports team only when that team is performing well. I've been rooting for the home team in their playoff run, but I'll admit I'm just a fair-weather fan.

To do or say something to make an argument, problem, or bad situation worse; to further incense an already angry person or group of people. The debate was going poorly for the senatorial candidate, and his strikingly uncouth comments simply fanned the flames. Revelations of the CEO's massive retirement package fanned the flames for consumers already furious over the company's dubious financial dealings.

To become more of a problem or more widespread or publicized. Once this scandal hits the fan, all of our investors are liable to pull out of the company.

rude slang Things become suddenly very chaotic, disastrous, difficult, or controversial. The company has been trying to distance itself from the outspoken director before he says something horribly offensive and the shit really hits the fan. He seems qualified on paper, but how do you think he'll perform under pressure when the shit hits the fan?

rude slang Some situation will become even more problematic, detrimental, or difficult to deal with. We're under a lot of scrutiny now, but the shit is really going to hit the fan if news of this payoff goes public. Shit is going to hit the fan if mom and dad find out I took the car out without their permission.

Aspects or material that are not officially part of the source material (of a work of fiction) but that fans promote or think could logically exist or occur in the source material. Also known as "fanon" and "head canon" (although the latter can also be applied to an individual fan's ideas, as opposed to those that have gained widespread currency). That pairing must be fan canon because I definitely don't remember seeing those two kiss in any episode of the series.

The act (by writers, creative directors, etc.) of attempting to please the fans of a work of fiction (typically a TV show) by depicting or incorporating certain aspects or character pairings that fans have promoted, requested, or shown interest in. With all the callbacks to the previous 199 episodes, and allusions to the interests of the show's rabid fan base, the musical episode of Supernatural is total fan service—and I love it.

Someone who strongly likes, appreciates, supports, and/or is interested in someone or something. You might find this hard to believe, but Cheryl's a big fan of heavy metal. I'm a big fan of Jen's new boyfriend—especially after the parade of losers she's brought home over the years! Sorry, but I'm not really a fan of Art Deco.

To begin to like, appreciate, support, and/or be interested in someone or something. You might find this hard to believe, but Cheryl's become a big fan of heavy metal over the years. I've become a fan of Jen's new boyfriend, and, yes, the fact that he brought me fancy chocolates did help!

To chat or converse aimlessly or casually, without any serious topic of conversation. Customers always want to fan the breeze with me in the store before they buy something. I just fanned the breeze with John for a while when he passed me on the street.
