This dipshit who has the audacity to attack the weakest people randomly because they think they're the shit. This species of garbage is mainly located in YBA, this garbage game where people are toxic. Stay away from these rkers because they haven't took a shower, touched grass, or have friends. People who are rkers will most likely get killed by a team of rebels who want to kill rkers.
Friend #1: Hey friend, someone just killed me! He's a rker!
Friend #2: Don't worry I'll help take them out. Lemme call Friends #3-10 so they can help too!

A RKer or "Random Killer" is a stupid term used by stupid people to complain about them sucking at the videogame and to look for an exuse to team on somebody. These people usually use the logic of "but they attack low levels" despite the term litterally meaning RANDOM killer. This is usually used as a last itch effort at an insult after raging because you SUCK AT THE VIDEOGAME FUCK YOU

An rker is someone who randomly fights someone because they maxed out everything and expects everyone else to e maxed out, they usually hang out near spawns or quest lines sine those places are filled with people who just started the game and they usually just kill them because the game doesn't have a system where you have to be a certain level to fight like bro i just wanna finish the quest line
