Why did a school shooter get banned from a game server?
He was caught aimbotting.
Listen up, buttercup. This joke is saying the school shooter got banned for using an aimbot, which is a cheat that makes your aim perfect in video games. The joke is funny because school shooters already have good aim in real life, so needing an aimbot is like needing a fish to swim.
