As friends you often throw (what you believe to be) harmless insults at each other, nothing meant to hurt each other's feelings just something to get a laugh out of each other. Typically when my friends joke around and insult each other I just laugh, and laugh too when they do it to me.
However on rare occasions they will often make a joke or insult that actually offends me and hurts, I usually laugh it off in these situations, but is this the right thing to do? I don't want to try and tell them to stop completely as there's no trend into what does and doesn't genuinely offend me, and I would feel a if I was being unfair if I just asked them to stop all together (besides I enjoy it usually). So what's the best way to react to a joke about you that genuinely offended/hurt you unintentionally.
