Basic Trope: A male character is raped by a female character, but is ignored or not taken seriously
Straight: Betty rapes Alex and gets away with it.
Betty keeps Alex locked up in a basement, raping him daily in the most horrific manners possible, with little food or water. When Alex manages to free himself from his bounds, he tries contacting his friend, who is ecstatic to hear that Alex is finally getting laid.
Betty is a thirty two year old babysitter who (often violently) rapes Alex from the time he is eight to the time he is twelve. Alex tries to tell his parents, but they blame him for having sex too early. Betty gets away scot free, and Alex's parents refuse to press charges.
Betty sexually harasses Alex and gets away with it.
Betty rapes Alex, and is reamed for it, and thrown into prison.
Double Subverted: ...but the sentence is short, and nobody remembers the incident afterwards.
Parodied: Betty commonly humiliates Alex by using force or threat to make him go shopping with her or to the nail salon. Everybody just laughs at Alex holding a pink handbag for Betty.
Zig Zagged: Betty rapes Alex. The police come by and arrest Betty...for throwing the used condom on the ground instead of throwing it in the trash. Then, the police discover that she raped Alex, and that turns her littering offense into a much more serious one. While carting Betty away, the officers laugh at Alex for letting himself get raped.
Averted: Betty rapes Alex, is brought to court, found guilty, and gets a punishment just as bad as if the genders were reversed.
"Betty didn't rape Alex. Women just can't rape men, do you hear me? They just can't! It doesn't happen, never did, never will!!"
Because nobody thinks what happened to Alex was rape, he is unable to deal with the mental problems he has. He develops a serious drug problem, almost dying from overdose on multiple occasions. He refuses to get help because all his former friends told him that he shouldn't be complaining. He eventually distrusts everyone, becoming a recluse. After attempts to press charges fail, Alex acts out against society by committing crimes. He eventually dies bitter and alone.
After being raped by Betty, Alex hates all women. This results in him subconsciously seeking out revenge, murdering or raping any women he sees who has the same hair color as Betty. When the cops try to arrest him, he decides to first get one last murder. He goes to Betty's house, shoots her to death, and turns the gun on himself.
