Homicidal Irony

Homicidal Irony is when someone threatens someone else's life with such an outlandish threat, that it deminishes the threat into something laughable.

Person A: I'm going to rip your spinal cord out and use it like a belt
Person B: haha that was some nice homicidal irony.
Person A: I'm not fucking kidding. Like I'm actually going to rip your head off and feed it to my dog.
Person B: Good one man
