Bullet reply

A bullet reply is basically a reply that you say on social media when you really want to diss someone who said something that irritates you but you don't want to go too over the top so you don't seem too butthurt. The bullet part is an analogy, basically think of how a bullet is small but it can kill someone just fine. That's basically it, you send a reply that's not an over the top insult, but it gets the job done just fine

Person 1: Damn this guy irritated me
Person 2: Did you ignore him?
Person 1: No, it would be best to do so, but I sent him a bullet reply instead
Person 2: Good shit, that'll teach 'em
