When a teenager is constantly being picked on (by friends) and it starts to get to their head, something changes. This change is that they start wanting to kill everyone in their path. If they were serious about it, this would be called, "Genocide." However, usually they just need to imagine killing everybody and maybe tell one friend so it is called, "Jonahcide".
Person 1: Why is everyone picking on me
Friend: That's how its always been
Person 1: It's so annoying and unfair
Friend: yo dude calm down, this never bothered you before
Person 1: Idk bro, its really getting to me. I'm ready to commit a major Jonahcide.
