An affair with a predetermined beginning and end, allowing a couple to grow as close as they want to during the affair without complicating their lives after the predetermined end.

The term was coined after the character Mitch Buchannon of the TV show Baywatch. Mitch needed to be presented as a romantic heartthrob capable of love, but one who, in order to keep the show interesting, could never be tied down. This forced writers to send all of his loves off to the other side of the world, whether for scientific research, caring for a dying parent or to "find themselves".

This allowed Mitch's heirum to transcend the superficial booty-call status but fall just short of marriage and permanence.
E- "Wow, Steve, do you have a girlfriend now?"

S- "No Eric, Why?"

E- "Who was that girl you were with the other night? You two looked like newlyweds, and you seemed so much more than eachother's bootycall"

S- "Oh, that was my Buchannon affair, Nikita. She has some important job in Russia and comes here for a few weeks once a year for recertification or something. Since we already know when she's leaving, it allows us to be as close as we want without worrying about anything too long term.

E- "Oh, like Mitch Buchannon, I get it..."

A woman who, whether intentionally or not, makes you consider cheating on your wife.

She is often your wife's younger, sexier sister or friend, that you flirt with because you really want to screw her brains out. However she could just be a random slut you encounter in a bar, shopping mall, or on the street. Affair bait typically does things that your wife doesn't, like give head and have anal sex.
My wife's friend just texted me, saying she's super horny, drunk, and lonely ... God she's total affair bait. Too bad I'm stuck at home watching 20/20 on television with my lame wife.

Like a real Affair, a Facebook Affair is when someone is cheating on their boyfriend/husband or girlfriend/wife with someone on Facebook. The relationship never really becomes physical and the two people might never actually meet. The Facebook Affair ranges from them sexting eachother and having very sexual conversations like they are a couple, to flirting and giving eachother "cute" nicknames like "honey" and "boo".

This can go on for months or be a one night thing. The two people may actually know each other or be complete strangers, but either way when the person they are actually in a relationship finds out there will be hell to pay.

A pop psychology term which instills a sense of impropriety when describing Platonic and courtly love (and other forms of intimate non-sexual association). Since the relationships it defines are by definition chaste, its use is misleading and is often used manipulatively.
