I imagine the dude getting murked is packing a tactical insertion so he'll repeatedly get killed by his friend and soon enough a killstreak ensues. This probably leads to a killstreak combo ending in a tactical nuke. It's gay as fuck when I don't know how you can enjoy getting something you didn't earn. You can't really doing anything about it except leave the room. I did that and encouraged others to leave as well as this would prematurely end the game before the nuke arrives.
