When someone is having major issues in their life that are totally unrelated to you but for some insane reason they are taking it out on you. You are now collateral damage in a fight that they should be having with someone else.
When Julie caught Tommy cheating on her she became convinced that all her friends were sleeping with him. She exploded on everyone and we were all collateral damage.
