When a girl has sex with a guy because she feels sorry for him. This can be a boyfriend that she is no longer interested in or a guy who follows her around with sad puppy dog eyes.

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.

The act of having sex with someone as a consoling gesture, immediately after breaking up with them.

The true purpose is to allow you a safe window of opportunity for collecting your property from their house.

(This generally occurs within an hour or two of the breakup, but it can sometimes qualify as a sympathy-fuck even a few days later if circumstances are extremely bad)

When you have sex with someone just to cheer them up. Most often in cases of boredom. Comes with no strings attached or emotional investment.

When a girl fucks a guy she feels sorry for, like he's her cousin from the side of the family who all died in a car accident when he was 3 months old. Or like an orphan, some kid with no family. Girls have sex with a guy like this thinking it will make the guy less likely to stalk or rape, when in reality this is the sort of attention a rapist or stalker dreams of. Likelihood of heinous sex crime victimization actually increases after a sympathy fuck.

Fucking out of pity or pressure
