After getting assaulted Charlie, Bob's friends laugh hysterically when he gets back.
After Bob gets assaulted by Charlie, he is considered gay and gets prosecuted under his society's sodomy laws.
Bob's friends laugh hysterically while witnessing the assault, and even Bob himself jokes about the incident later.
Downplayed: Alice and Bob get both raped by Charlie in a quite traumatic incident. While their friends and family react appropriately to their disgrace, it is also quite obvious that they are more worried about Alice than Bob.
The story is set in a time period or culture where this really would be laughed at instead of treated seriously.
The fictional scene is played as a Dark Comedy in which the Big Bad is on the receiving end.
Bob's friends heard an anecdote about a rape story and they thought it was a funny dirty joke until they found out that Bob was the victim, and then they become immediately apologetic & supportive after they know the truth.
The joke's actually on the rapist - Bob was Betty when it happened.
Exploited: See "Invoked", and and consider that the guy is using his argument in order to minimize his punishment and/or to get sent to a less awful prison (or to avoid having his fellow prisoners beat him up because male on female rape is a special kind of evil).
Defied: The incident is treated seriously in story and the majority of viewers would never find it to be the least bit Narm.
Discussed: "Want to hear something really funny? Bob claims he got raped by a man!"
Conversed: "Ever noticed how comedies throw a gay rape scene in the middle and everyone is too busy laughing to call the police?"
Deconstructed: Bob gets raped by another guy and seems relatively unaffected by it—but when he meets up with a trusted confidante, he drops the facade and is shown to be realistically traumatized and humiliated. The confidante fails to actually help (or laughs at him), causing Bob to withdraw from life to try and distance himself from his feelings. Eventually his friends realize that rape isn't funny when anyone does it and try to help, but their efforts come too late and Bob, convinced that he has no other options, is Driven to Suicide. His friends are left guilt-ridden and shaken, both by the actual loss and the fact that they should have prevented it.
The suicide attempt fails and Bob gets therapy, eventually overcoming his trauma and starts a charity for male rape victims.
Alternately, Bob's friends prevent him from killing himself and become a reliable support system.
A dark comedy has the moral of "Although this is Played for Laughs, like everything else about dark comedies, these gags should never be taken seriously."
