An RKer is someone who has sex with cats. He thinks the cats like it but they don't. Poor cats.
"Why did Jason just buy a new cat?" Asked Travis. "He's an RKer." Jake said. "I always knew thats what he meant by getting pussy!" Said Henry.

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!
