When people use their dying breath to yell "IT'S THIS PERSON!" That's not a KOS fam, and now you're dead.
When I spend more effort spamming the kos button rather than shooting the traitor that is killing me and people just decide to forget how to read and spend some quality time skipping along and exploring the map with the traitor. Pro tip: if you are only kosed in chat, don't buy a disguiser. People will read it out loud in the voice chat and then you can buy it.
When your Det or T buddies shoot you out of nowhere and kill you instead of the person near you, fix your aimbot pretty please
When you’re in a firefight kosing the T in voice and text chat and someone STILL comes around the corner and kills you. When your T buddy throws a made, and at the same time of releasing the nade presses their bind for a nade only giving you a couple seconds to get out of the way. neither is worse than the other. Both still make me alt-f4
Wait how tf could I forget, when you go get all the chests for the secret knife on seriouscraft then someone either activates it and takes the knife first or pushes you out of the way and take it.
